1) I'm going to trust the hunches of evolutionary biologists over the hunches of OP
2) Humans really aren't that different from apes, 7 million years is plenty for such miniscule evolutions.
3) The 'they didn't evolve because they didn't need to' argument is very reasonable, and it's going to take a lot more than you simply saying it's not true to convince anyone. Something like a crocodile, any additionall features (hands?) it evolves, will simply use more energy, and thus they will no longer be able to get enough prey) crocodiles don't evolve because there is pretty much nothing that kills them (except humans extremely recently, too short a time to evolve), a miniscule number of them don't have enough food, because they need so little. What is there to stop even the least fit crocodiles from reproducing?
