That sir, is a lot of text.

Right, OK...

"But...what we're doing to the evolutionary chain ISN'T natural. It cannot be taken as simply a natural disaster, because we've obtained our position through unnatural means, and the damage we've done as humans is FAR greater than any disaster that has ever occurred unless you consider the global flood. (which, btw, if it happened would have erased and corrupted the time tables for everything that came during or before it, which would mean, if it did happen, we would have absolutely no way of accurately determining the age of our planet)

Plus, you have all the partial eradications, like the Grey Wolf in North America. We erased it from the land, which did a LOT of damage to our eco-system. Sure, we're trying to get it back, but it's not really going all that well 'cause people are idiots.

And without the wolf, forests got ravished by deer, cougar and coyote populations exploded. No wolves probably helped the wild bore and other evasive species flourish in America. Evolution implies that, for it to work, a species would have to have a reason to evolve; a weakness or a predator to overcome. But, without that motivation; that ingredient, if you will, wouldn't the Evolutionary process cease to exist?"


I'd like to take you up on a few points here. Firstly, I would dispute what natural is. By extension, the question I propose is, essentially, "what is natural?" :) The expansion and growth of a population of a species is a phenomenon that occurs all the time. This, when the growth is big enough, can lead to it affecting the wider ecological system. This is what is occurring in humans (and deer etc.). This is not unusual (although shaping our environment in quite the way we have is unusual, it is merely an extension of practices we see in many species the world over), even if the growth effects of our existence is unsustainable, history has shown that those out of balance with the wider system will bring about a counter measure (such as a virus killing itself off by killing its host - a pattern some draw parallels with to humans as well, it's worth noting, and what I believe you are implying, which I agree with). So we will either pull ourselves back from the "brink" or not and one of two things will likely occur:

1. Nature gives us a major kick in the arse by nearly wiping us all out (read: plague, Bird-flu, air pollution etc.)
2. Our effect is so damaging that the ecological system we rely on totally collapses under our weight.

It is up to us to take control of the situation and get a handle on it. Easier said than done, though! Especially since some people now believe we aren't even doing any harm to the planet! According to sources cited in the wikipedia article, less than half of republican respondents to a survey on the issue were convinced of the issue even existing!!!

Are you linking small changes and the law of consequences bringing about large-scale change similar to the butterfly affect (thanks to human expansion) to a wider "ecological balance" on which EVERYTHING depends (or at least large sectors of life)? Again, I would be inclined to suggest that you're probably right. On the process and our increasing influence on it (for better or worse: probably worse).

I'm not an expert, but I find it quite hard to believe that there is absolutely no way that we could determine the age of the planet (aside from the fact that we already know) after a flood. Also, the global flood you mention (which I had to look up as I'd never heard of it!) apparently has little scientific validity outside of creationist circles. I can't really comment on this since whether it even happened (as you have acknowledged yourself) is doubtful.

"Also, human beings have demonstrated that they have the power to essentially control what lives and what survives. We could even wipe out ourselves if we so desired. (It's harder to do with non-lethal methods and big cities, but that does not mean we do not have the power). To me, because we humans possess that power, Evolution, if it did exist at one point, has stopped. As soon as we committed our first act of genocide, Evolution would have halted. Sure, nature would have done it's best to correct our power, but we are just too powerful."

I don't think we necessarily are. Niky, a few others and I were just discussing in this very thread the issue of superbugs. Cancer, HIV and other conditions seem to keep emerging. The human race has managed to prevail thus far and I am confident (although speculative) that we'll continue for many more years. But nature keeps throwing-up curveballs. Some of them (like the plague) really hammered the human population. But who knows, maybe we'll form some part of a "league" of 'things' that can exist in many places (like bacteria and water). But we'll certainly have to be very careful and respectful of the environment in which we exist to maximise our chances.

"No one can say for sure how this earth or the creatures on it got to where they are today because no one alive was there when it started. Not even prophets can see that far in the past. But, it has been stated many many many times in the past that human beings are powerful. Even in the Bible, God mentions that we are like gods (Gen. 3:22) and we have such great power that not even heaven is beyond our reach. (Gen 11:6) (And didn't the Greek gods eventually fall victim to the power of mortal men?)

There all sorts of things that we have done that would have decimated the flow of Evolution. Domestic dogs, domestic cats, cows, modern chickens and turkeys (which, by the way, can no longer breed on their own)....My point isn't that we've simply disrupted evolution, we've completely stopped it for MANY species. We, in our current form, would be the ultimate evolutionary specie because of our power."


Because of our dominance relative to our environment? Yes, I'd agree with that. Although our power isnt so all consuming (which relates to my point on super-bugs). I can't really comment on quotes from the good book though. I can only really deal with facts (and then create my own conjecture!) when trying to tie everything together into some form of understanding.

"If we can stop the evolutionary chain of events, if we are the fittest specie, then wouldn't "man-beasts" be the ultimate end to evolution. Then every specie would be on level ground. There would be no fittest specie anymore."

Not sure I follow you, here.

"(By the way, if you consider we are at our Evolutionary fittest point, then that means we would have arrived at this point BEFORE everything else, which would imply that the Evolutionary flow was out of balance from the beginning...and maintain it's out of balance ways through several mass extinctions if you believe in those. And correct me if I'm wrong, but that isn't how Evolution is supposed to work. I'm starting to see why Darwin himself had issues with applying his "theory" on much larger terms, 'cause when you REALLY start to think about it, it doesn't really...work. 'Cause humans don't entirely fit.)"

You are implying that everything that evolves does so to reach this specific point. It is worth noting that everything that evolves does so relative to its environment. So, fish evolving over the last few million years would have had a different set of goals than we would, for example. I agree, we don't fit though. Humans are still continually evolving. Although for us, our environment (and our skills at adapting) seem to be much more rapid than other species. So, we could be the first species to live by another set of rules (which is really just a complicated, sped-up version of the old processes, such as us being more flexible to our environments: driving, flying, swimming etc. Feral children are a good example of how adaptable we are. You don't see dogs learning to drive, do you?! :P )

"Now...if one were to say humans were the caretakers of Evolution, then that makes more sense....but wait...weren't we called "caretakers of the land" somewhere already?

Oh yeah:

"And God blessed them. And God said to them, "Be fruitful and multiply and fill the earth and subdue it and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth." -- Genesis 1:28.


EDIT: P. S. I'm not saying the Bible is right or literal or anything like that. I'm just saying human beings are powerful enough that even the writers of the Bible acknowledged our power. As for the homosexuality thing....if you want to go with the Evolutionary theory, then it would simply be nature...which definitely isn't something most Christians want to acknowledge. As for me, I have no idea why homosexuality exists. A lot of naturalists believe it shows an extremely close bond between members of the same sex..."closer than family" if you will. And that maybe what it was, at one point, with humans, as well. But, as with all animals, we humans are pretty darn unpredictable and I think to answer the question as to why homosexuality exists in so many species, we would have to ask them, but, if we did ask them, we'd better be prepared for every specie to give us completely different answers."


Um, this is where we might differ concretely. I can't really take much theological text to help form my understanding of the world because it doesn't fit with my model for reliable information. Not saying it's worthless, but I have no reason to believe it to be anything of use to me personally. Since your whole point here is based on it, there's not much I can say...

...well, that and animals that can respond to our questions on homosexuality in a coherent fashion (or at all), to which there is also not much I can say...

I am sure with what I already know. If I am wrong, prove me wrong.

I have never said such thing, nor have I said that the existence of God has been proven at all.

There are literally thousands of examples that clearly explain how evolution has taken place and even in the micro sense in that those living at different elevations will have slightly different body composition. That sir is evolution and adaption, no? I've studied evolution myself in Biology 101 with looking at skeletons (pictures) of how slowly certain parts of organisms slowly transform from one structure to the next.

There are exactly 0 explainable theories on how exactly an all powerful being could create a human from nothing. Now if you believe in that sort of thing fantastic then stick to it as the power in believing something is truly extraordinary, as for proof however your not going to find much.
 
I thought this was worthy of attention:

"It is the essence of all scientific theories that they cannot resolve everything. Science cannot answer the questions that philosophers - or children - ask: why are we here, what is the point of being alive, how ought we to behave? Genetics has almost nothing to say about what makes us more than just machines driven by biology, about what makes us human. These questions may be interesting, but scientists are no more qualified to comment on them than is anyone else." - Steve Jones, Professor of Genetics at University College, London

Of course this contributes nothing to the evolutionary discussion, but it is just an interesting pointer. We are more than simply machines.

There is nothing to comment on. There is no 'why', there is only 'how'.

Now, will you please stop posting useless quotes before you embarrass yourself too much?

Simple solution, there is no answer.

Nonsense. Human DNA, that's what makes us human.

What in the world does that have to do with anything? I think your in way over your head on this topic. If 95 is your birth year you've yet to even take upper level high school biology let alone university level stuff.

It was just a quotation stating that we are more than mere machines...
And if we are nothing more than animate blobs of matter, why should I temporarily help or comfort my fellow blob of matter, if we are all going to face the same inescapable doom of death anyway?!

Such thinking is inescapably pessimistic and nihilist. It is potentially dangerous too. If our own thoughts are controlled by nothing more than atoms, then discussing morality is laughable. As I have already brought forward in the God thread:
"Thinking atoms discussing morality is absurd." - Ravi Zacharias

I also believe this nullifies your explanation to the meaning of life (to reproduce). If there is no real meaning to life, then why bother.

One could say that the meaning of life could be explained in such a way as this:
"Eat, drink, and be merry, for tomorrow we die!"
This seems rather pleasing at first, but it's a little bit selfish. If the purpose of life is purely to find some kind of happiness, what happens if one finds amusement in invalidating someone else's joy? If one finds happiness through murder or robbery, who are you to say that it is wrong? After all, doesn't morality get chucked out the window with such view in life?

And here I am, believing in faith (not blind faith, remember) that gives me purpose in life, and I am called deluded by atheists in my community for doing so?

I find this rather insulting. Congratulations if you wished to achieve it.
I am not a man of academics, but that doesn't stop me from trying to learn.
My point I was trying to make, is that humans are more than machines. I thought it was relative to the discussion, not particularly in favour of evolution nor against it. If it is so irrelevant as everyone says it is, then why doesn't a Mod delete it then. I'm sorry guys.

He briefly explains his opinion on where morality, or what most humans consider the right thing to do, comes from and why we are really just animate blobs that do have a reason to care.


I watched Steve Jobs' commencement speech at Stanford recently and he talks about how impending death is the best motivator for life or something along those lines. The part about death is around the 9minute mark.

Pessimistic? Not in the slightest. Dangerous? For the weak minded perhaps.

Why help the blob of matter? Because mutual cooperation tends to raise everyone's happiness. Or can blobs of matter not feel happiness? That would seem like a silly statement considering it happens all the time.

What's really silly is saying that we need a purpose to care about other people. That's just ridiculous. I wonder if religion was all proved to be wrong without a doubt. Would the religious people of the world run off to live in caves and then attack everyone else since God and religion was the only thing running their lives?

I also believe this nullifies your explanation to the meaning of life (to reproduce). If there is no real meaning to life, then why bother.
Life has no meaning, not even to reproduce. Life reproduces because it developed that ability. It's as simple as that.

"Eat, drink, and be merry, for tomorrow we die!"

OK, but that quote above probably doesn't sum up the view of anyone in the thread. In fact if I'm remembering correctly phrases like that came from Christians after they were left troubled by the inexplicable death caused by the bubonic plague in Europe. But anyway, you can try robbing and murdering, but all the other blobs of matter who are here for no reason (or at least the majority) won't like that. It's why they made these things call laws. There might not be any meaning to life, but that doesn't stop someone from enjoying life and protecting their own life.

That's where morals came from. People realized that if anyone could do absolutely anything, it might cause someone else pain. Then, people tried to decided what would strike the best balance between individual freedom and the good of the human race as a whole. It's changed with time as we thought more and the world changed, but that's where it comes from even now.


And here I am, believing in faith (not blind faith, remember) that gives me purpose in life, and I am called deluded by atheists in my community for doing so?
Faith is blind faith pretty much. And your ideas above really show a lack of understanding. None of it even has anything to do with atheism anyway.

So long as you're seriously trying to learn, there is nothing to apologize for. However, repeatedly mixing up facts and repeating falsehoods, even if by mistake can annoy other people. I'm not taking sides here, just giving advice.
 
Your quotation was a scientist pointing out that science does not exist to explain the why of anything. He's defining his subject matter by pointing out, up front, what it ain't.

Science is not Philosophy.

He never said science can't answer questions, he said it can't answer those questions. Those aren't scientific questions.

Talk about out of context!!!!!
 
Macro evolution has not been 'proven' at all. No one has observed a complete example of macro-evolution taking place.

As pointed out, Famine has noted an example of "macro" evolution being observed recently in this very thread.

Before saying something hasn't been proven... you have to find out if it really hasn't, then tell us why the proof isn't proof.

Which is beside the point. There's no difference between marco-evolution and micro-evolution. Enough instances of micro-evolution will eventually lead to macro-evolution.

It's funny you think that was insulting. I'm saying you haven't posted your own thoughts at all, as others have pointed out, and then get defensive when people point it out. If you are seriously trying to learn then do that and take in others opinions and respond to them with your own. I couldn't careless if your wrong with something you say, as far as I know I've been wrong many times on here. But stop posting lengthy irrelevant posts and put down some of your own opinions.

The questions that Steve Jones mentions are ones that science (or anything else for that matter) doesn't currently answer, and maybe never will - but they may well be questions that have no answer.

The very act of asking a question begs an answer, but not every question has an answer - it depends on what you are asking and if the question makes sense. But science is not just about finding answers - it's also about finding legitimate questions to ask. Armed with enough facts, science is quite capable of answering many 'why' questions. But there will always be questions that simply cannot be answered. In a funny way, science does go some way to answering such questions by establishing that the question doesn't make sense in the first place and therefore does not have a legitimate answer at all.
 
Far off-point for this thread, but I am reminded of a note from "A Brieft History of Time" by Stephen Hawking. Where he says that he hopes, in time, people who are not incredibly gifted mathematicians can begin to understand the fundamental nature of the Universe, thereby shifting the questions of the Universe and its origins back to the philosophical. He cites this as one of the reasons for him releasing his book in common language without a single mathematical equation (besides E=mc2, which is put there merely as a reference).

Back on-point, this is the problem with Evolution. It is very hard to debate Evolution if, even though the data, premises, hypotheses and the resulting theory that has been developed and which is supported by (literally) mountains of evidence are available to the public in the common (non-mathematical) tongue, it's hard to get people to educate themselves about it.

In this case, we are hung up on whether or not Eve has one more set of ribs than Adam, and not whether the intrinsic quantum mechanical nature of the Universe was pre-programmed to lead to compex carbo-structures and, eventually... life.
 
The only reason for antibiotic resistance not becoming fixed globally is because there are so many different strains and substrains of different kinds of bacteria that there are bound to be populations of the bacteria that are resistant and populations that aren't. Yet there is a growing unease amongst health professionals about certain strains becoming resistant to more and more antibiotics. We're running out.

As for evolutionary change in large populations... one of the posited reasons for our evolutionary leap in intelligence is a crucial point in human history when the entire Homo sapiens population was reduced to just a few thousand individuals. Mass extinctions (like the one we are going through now) and population isolation (such as occured in Australia and Madagascar) are great drivers of evolutionary change.
I think the title of this article says it all.
"Antibiotic resistance is ancient".
All our antibiotics is doing is killing off the bacteria that has no resistance which makes more room that does. In most cases when an antibodic is removed from an area the non-resistant bacteria will again start out-multiply the resistant strain. Thus it's wise to rotate antibiotics.
I remember reading an article that lab studies (more ideal conditions than found in nature) they haven't been able to get a "soft" selection to become fixed in a population of sexual creatures. These are the main mutations needed to drive evolution. Thus evolution is more affective with asexual than with sexual creatures.
Macro evolution has not been 'proven' at all. No one has observed a complete example of macro-evolution taking place.
You have to be careful making a statement about macro-evolution (I know what you are saying) as evolutionist will use an example where a mutation or two can change the structure of a creature. We already have examples of where big differences are not due to genes. Just look at axolotl for example and how much difference a few iodine atoms made. (Of course they wouldn't use this as an example since this wasn't a result of a mutation.)

Not really that surprising. Many mutations that create radically different characteristics merely reactivate old traits or deactivate current ones.

Lactose Intolerance is an interesting case (a few hundred pages back) where Lactose Intolerance amongst adult humans used to be the norm, until a random mutation turned it off... creating a neotenous trait in modern humans (neoteny... meaning we have kept a trait once possessed only by immature humans... children) allowing adult humans in certain populations to drink milk. This is part of what helped ancient Europeans spread out.

Then there's scurvy... the result of a mutation that causes humans to not manufacture their own Vitamin C.

-

Of course... for the antibiotic to be effective in the first place, the gene for the resistance has to be "off"... and the bacteria are killed off en masse, until and unless a random mutation turns it on again, or a population of a certain kind of bacteria steals the gene from another kind of bacteria.

-

Lab studies, of course, don't have the time available to nature. That it's hard is a given. That it's impossible isn't. What is needed is not just to select traits (hell, dog breeders and goldfish breeders have done that successfully for centuries, and the breeds always breed true), but to create a condition wherein populations with different traits have time to accumulate enough mutations so that they can no longer interbreed (see below).


You have to be careful making a statement about macro-evolution (I know what you are saying) as evolutionist will use an example where a mutation or two can change the structure of a creature. We already have many example that has shown where big differences are not due to genes. Just look at axolotl for example and how much difference a few iodine atoms made. (Of course they wouldn't use this as an example since this wasn't a result of a mutation.)

I'd argue that the Axolotl is a prime case of mutation. Because the gene that gives them the ability to produce the hormone that causes them to transform into "adult" salamanders has been turned off. The iodine merely serves as hormone replacement, which then triggers the transformation.

Structural differences per se don't mean much (see dogs and goldfish), but there is no doubt that they can become fixed in a population and genetically encoded given time and isolation. Otherwise a Chihuahua and a Chihuahua of fully authenticated lineage would sometimes produce a Terrier. It takes time and population isolation to speciate them.

This is why Zebras and Horses, despite having very little in terms of structural differences, can only partially successfully mate (producing a mule), whereas a Chihuahua and a Great Dane, despite the vast difference in size and appearance, could... if you could find a way to make it work.

Since the DNA is already fully loaded with information enzymes like nylonase are very easy to evolve and can be easily repeated. Now the ability to shot web out your butt (or hands like Spiderman) is a lot harder to do even if you add in spider DNA. (Now mutation where you lose something is very easy to come as the road to destruction is wide.)

Lab studies, of course, don't have the time available to nature.
Evolution is not about time but generations. Also lab have scientist to greatly speed up the process and add in the perfect conditions.

Neoteny and destructive mutation explains a lot. Why we only have four limbs and five fingers or toes on each extremity. Why we only have hair in a few places. If the argument is that the creation of new features isn't provable, then go Galapagos. That's evolution in action over successive generations, through small, incremental steps.

Evolution is not about time but generations. Also lab have scientist to greatly speed up the process and add in the perfect conditions.

How many generations do you think it takes?

Zebras, horses and donkeys can mate. With horses and donkeys, you get a mule. With horses and zebras, you get a zebramule. Both mule and zebramule are largely sterile due to imperfect coding.
 
Zebras and Horses mate quite successfully, actually.

I also want to point out that the fact that we have 98% of our DNA in common with chimps is a really big "And?" All life on earth only has 4 base pairs, meaning, we have 98% of our DNA in common with pretty much all life on earth. (or around there, anyway.) If we had 21 base pairs or something, then, yes, 98% would basically imply that we're of the same specie as chimps, but, as that's not the case, then it's not really impressive...at all. Especially when you also take into account that a if you were to switch two base pairs around, you'd get something completely different. With small adjustments to the DNA producing such great variety...again...98% isn't anything to throw a party over.

It should also be noted that, before technology entered the scene, human beings had lots of competition and thus, a need to evolve. But...now...we don't really have any need to evolve again. So..yeah, the more I think about it the more I am sure that we human beings have come to our evolutionary peak if there is such a thing and we'd just be encouraging the animals to evolve.......in ways they probably wouldn't if we had left them alone.....yeah....it's crazy.
 
An evolutionary peak is unlikely. As long as the world goes on, there will be evolution. Just wait until people leave for Mars, humans will probably separate into multiple species at some point.
 
Exorcet

I agree. As one species evolves another has to evolve as a result or risk being wiped out. In turn another, then another, and then another species must evolve in one massive chain reaction. Of course when some species don't, they go extinct.
 
Zebras and Horses mate quite successfully, actually.

Successful mating doesn't only mean you can get the mare pregnant... but that your offspirng can have offspring of their own. The first part is easy, the second part is very, very hard.

That's why the term "mule" is often used as a generic term to denote the sterile offspring of two different but related species... because mules usually can't reproduce, and breeding mules and other equine hybrids is very, very, very, very, very difficult. If you can't create a breeding population that doesn't need genetic input from outside, you can't create a viable species.

The human genome is still shifting, but given the interconnectedness of the modern world and the shrinking and dissolution of small pockets of humanity that carry strange genes or features, a massive shift in our genetic make-up is not likely any time soon.
 
An evolutionary peak is unlikely. As long as the world goes on, there will be evolution. Just wait until people leave for Mars, humans will probably separate into multiple species at some point.
I think any evolutionary changes that happen to humans from now on will be through technology. Our ability to change ourselves is growing at a way faster rate than we've changed in the past.

I was just thinking the same thing. Whereas most animals adapt themselves to their environment, we adapt the environment to ourselves. In the mid-term, that could be our undoing if we run into some unforeseen adversary (because we'll be weaker than we otherwise would have been)... In the long-term (provided we survive that long), we may find things like our bodies to be used less and less in their natural states; certainly if recent trends are anything to go by (aka the emergence of the "sedentary lifestyle")...

On a very small level, the adaption of the world to suit ourselves has already resulted in problems, albeit not particularly dangerous ones. Allergies are a fairly recent (and increasing) human phenomenon, caused by excessive cleanliness in our environment. Starved of actual diseases to fight off, the immune system starts picking fights with basically harmless things like pollen and dust mite droppings, which is why we get allergies.

I'm happy to admit that I'm a bit lax when it comes to sweeping dust away. My room is full of it. Not in the slightest bit allergic to it. My ex girlfriend used to start sneezing straight away, and yet she excessively cleaned everything. At the same time, I've not had a pet cat for the best part of a decade now, and whenever I'm in the same room as one my eyes start itching.

I forsee a scenario, not that long away, where allergies actually become one of the biggest human biological problems, when we've eradicated all traces of other disease, the flu virus and everything else, peoples immune systems will become incredibly sensitive to non-harmful particles.
 
Zebras and Horses mate quite successfully, actually.
But their offspring are sterile, and that's what matters.
I also want to point out that the fact that we have 98% of our DNA in common with chimps is a really big "And?" All life on earth only has 4 base pairs, meaning, we have 98% of our DNA in common with pretty much all life on earth. (or around there, anyway.) If we had 21 base pairs or something, then, yes, 98% would basically imply that we're of the same specie as chimps, but, as that's not the case, then it's not really impressive...at all. Especially when you also take into account that a if you were to switch two base pairs around, you'd get something completely different. With small adjustments to the DNA producing such great variety...again...98% isn't anything to throw a party over.
You're missing the point. That 98% does not refer to the nucleotides themselves, but the order in which they occur. The DNA sequences of chimps are 98% the same as human while a mouse, say, has 95% the same DNA pattern as humans, a fish has 90%, etc (I don't recall the exact percentages here, but that's the trend).
It should also be noted that, before technology entered the scene, human beings had lots of competition and thus, a need to evolve. But...now...we don't really have any need to evolve again. So..yeah, the more I think about it the more I am sure that we human beings have come to our evolutionary peak if there is such a thing and we'd just be encouraging the animals to evolve.......in ways they probably wouldn't if we had left them alone.....yeah....it's crazy.
There is no "need to evolve". Evolution is blind, it is not goal-directed at all. Saying "an organism evolved a feature in order to ..." is completely incorrect. The new feature just happens to pop up. If it helps the organism to survive it gets passed on to its offspring. If it hurts survival it doesn't.
 
But...evolution is survival of the fittest. So, it IS goal oriented. Each specie would be working towards becoming the fittest. And I've always heard that "This species evolved, because..." or "they evolved to..." Although, I will admit, no one has ever mentioned a reasoning behind why dinosaurs evolved into birds. (And just because we have fossil records showing similar species with and without feathers, really doesn't mean anything. It could simply be that the feathers weren't preserved in one fossil and were in the other.)

And yes, I understand the 98% represents the order...but...as you pointed out, most things have a 90%+ similar DNA sequence with humans...If you're going by DNA sequences, then one would have to argue that EVERYTHING is related to everything else in some way.

And...I still don't think humans fit with evolution very well...even cavemen would chase entire herds of animals off cliffs and feed off the spoils. No other "animal" on this planet kills as much as we do. No other specie has made as much impact on the evolutionary chain as we have. We really are the top of the food chain. I would think that for evolution to REALLY work, there can't be a top of the food chain. Sure there are animals that can kill us and there are a few that could potentially be the above us on the food chain if they were discovered, but, I believe, even then, we would find a way to become the top again. We are the King of Beasts, masters of the land.

I don't know....every time I step back and look at the whole evolutionary picture, there just doesn't really seem to be a way to put humans in there without screwing up everything else. Also, there hasn't really been an evolutionary change in anything in a very long time....not since we homo-sapians rose to power. (Unless you count the human race wiping out several species an evolutionary change.)

Not quite.

What an individual does in his own effort to survive in his own skin has nothing whatsoever to do with evolution. No dinosaur ever thought to himself, "Holy crap, if I could just take to the air I could get away from this thing!!!!"

What happens is that some feature appears somehow, somewhen, and if the feature helps the individual survive, it gets passed to his descendants. There is no decision anywhere to produce a new color, or a new limb, or tougher skin, or feathers or hair, or glands to feed its young. Some gene copy somewhere fails, and produces a new trait. If the trait helps, it becomes permanent, simply by helping the body it lives in live long enough to have young-'uns.

That process is Natural Selection, which is a process through which Evolution can occur.
