That proves nothing except that the same Creator made them.
It proves that animals and humans have a lot more similarities than differences, and that is exactly what I was trying to prove.
But fine, if you want to talk about evolution then let's. It also proves that chimps and humans have common ancestors. There are MANY ways of building proteins with the exact same function and yet the more closely related two species are, the more closely their proteins match.
For example, if you compare the hemoglobin of humans, rats, chickens, and rhesus monkeys, you will find that human hemoglobin is the most similar to the rhesus monkeys, then to rats, and then to chickens.
They are all hemoglobin, the protein in blood to carry oxygen, but they're different.
The engine from a chevy will also fit into a pontiac.
If you compare the proteins from a shark and a dolphin, which both look very much alike, live in the same environment, sometimes eat the same foods, etc, you will find that the shark's proteins will be much more alike to that of any other fish, whether it lives in the deep sea, or whether it's a flying fish, than to the proteins from the dolphin. And the dolphin's proteins will be more like any other mammal than the shark.
If god had created each organism individually, you wouldn't expect such findings. You would expect organisms to be as closely related as one rock is to another (By that I mean that rocks are basically impossible to classify very well. Sure, you can classify them by how they were formed, where they are found, etc... but it's nowhere NEAR how you can classify organisms)
