But this assumes we would have needed them to die for us to survive. which is very possible.
But it also means that we were continuously smarter and/or more savvy than the closest competitor as well, something monkeys are apparantly not, even though we evovled from them.
It's certainly a long string of chance, at least.
Not sure I agree with much of that... here's why:-
1) No species
needed other to die for them to survive... the fact that one survives and one dies is because the species that is best adapted to it's surroundings will always have a higher chance of survival than one that does not... a species that 'fits' it's environment best will survive - hence 'survival of the
fittest'...
2) We did not evolve from monkeys.
Check out this site for a great tour of evolutionary history. (
This page is the stage where primates diverge)... Primates, which includes the great apes, which includes us, all have a common ancestor at some stage, but then again, if you go back far enough (which you can do on that brilliant website ^), everything (ultimately) has a common ancestor... more accurately, we should say that
chimpanzees (our closest evolutionary relative) and humans evolved from a common ancestor, current estimates put the split at somewhere around 4-6 million years ago... (try starting from the beginning and following the path to us - I actually posted the full chain a few weeks ago in this very thread too... gives you some idea of just how long (timewise) our full evolutionary history was... notice how late the dinosaurs turn up...
)
3) A long string of chance? Not really... that's the point of evolution... yes, a species gains it's advantageous merits by chance, but the reason any species survives (and hence evolves further) is not chance at all. As hinted at in point 1) of my reply, the species that is best adapted to it's surroundings will survive in favour over others which are less well adapted... (this is 'natural selection') This explains perfectly how many living things 'appear' to be perfectly designed for their environments... but this is just the
appearance of design. Infact, this 'perfect design' is achieved by the process of natural selection.
TM- what makes dolphins in your opinion, so much smarter than Monkeys, and Cats? I don't know any monkeys, but I know cats, and not only do they express a variety of emotions, but also other intelligent attributes as well.
Ever seen a cat "shun" it's owners? quite hilarious, but seemingly intelligent as well
Literally - sat in front of them, after they returned from a 4-day trip, turned around, and sat down, glancing over his shoulder, and snuffing them. for over an hour.
I'm not putting cats down - they are intelligent animals, and so are dogs - Dolphins appear to demonstrate a different order of magnitude of intelligence than other animals, e.g. they can communicate with each other, and have much more highly developed mental skills -
see this for some details/references. Cats and dogs are intelligent creatures, but on the relative scale of all living things, they are nowhere near dolphins, but head and shoulders above many more animals...
Debating why or how dolphins are 'smarter' than cats is really neither here nor there in the gran scheme of things (although it is fun
)... If we take another example, I could make the same point using dolphins v mice, or even cats v mice, or chimps v humans, or chimps v slugs... my point is that there is a broad spectrum of intelligent life, and we are at the extreme end of that spectrum - every other living thing appears
somewhere on the scale, and relative to other forms of life, some animals are vastly more intelligent (by our 'human' standards) than others...
