Do you forget which side of the fence I'm on. I'm not the one with the problem. When I get to heaven Jesus will pat me on the back and tell me nice try! When you get there all we will here is...but...but...we had fossils!
In my Bible Jesus does not appear until about 40 books AFTER creation.
God created a living breathing earth you silly boy!
One where the conditions for evolutionary change exist.
As the Earth changes, its occupants must also. Fossil jungles in the baked hard earth under the desert, marine fossils in the mountains of the American Southwest. It's not a generational thing; no animal has babies that are another species, which is what you're asking us to show you. We can't, and we never expected to able to.
The species itself changes over time (an IMMENSE amount of time) through tiny developments. Perhaps an animal has to reach for its food, so babies that grow tall survive more often. In 20 or 30 generations you have an animal that's exactly the same, only a couple of inches taller on average. Now they've moved from a savannah setting to more heavily forested area, and those babies of a certain color skin (or fur or scale or feather) survive more often, and soon you have almost the exact same animal, but a different color. Keep doing those tiny little changes over those tens and hundreds of generations, and soon the animal has no comparison to your starting point. There's no instant in time that you can point to and say, "This animal was
podunkus minimalus and this animal is
podunkus giganticus, but if you take one of the earlier ones and one of the later ones (enough later) you have a different creature, and one that cannot interbreed with the other; it's changed too much.
In a bifurcation, like the mysterious timeline you and "Earth" seem to have so much trouble with, you have a creature that follows two separate paths of development. One group goes one direction (perhaps literally, travelling one way through its habitat) and another group goes another direction, their descendants being "siblings" in the order of species. Such a bifurcation separates the ancestors of cats and dogs from each other. The fact that you asked for a "catdog" shows how little you understand what's happening here.
And don't confuse breeds with species. German Shepherds and Pomeranians are the same species. They can mate and produce offspring. Persians and Siamese are the same species also. Persians and Poms? No. But you must recognize the canine-ness of wolves, hyenas, and domestic dogs, and you must recognize the feline-ness of lions, tigers, and the domestic cat. There is evidence suggesting that domestic dogs developed as a species from early man's domestication of asian gray wolves. The traits became separate enough from wolves that dogs became a separate species. Please take a look at what that means: Dogs are a YOUNGER species than man. They owe their very existance as a species to the meddling of man, and the convenience he found in taming the wolf for help in hunting and guarding his homes.
