In terms of what happened with the environment, yes. And your facepalm only indicates to me that your ignorance is even more profound than I previously thought.
As I mentioned in my last post, if successful, this proto-ape would have reproduced and spread to other areas, undoubtedly in search for food. One of the problems with success is that an organism can begin to outstrip the local food supply, and this is true with humans as well.
In eastern Africa, there was a movement of plates whereas in the Rift Valley area, mountain ranges appeared, causing the eastern region to begin to go drier. With the consequence of forests giving away to savannas with fewer trees, this forced many species to either adapt or go extinct through the process of natural selection. It is this environmental strain which appears to have forced adjustments for our ape-like ancestors in that region, encouraging upright bipedalism that clearly shows up in our earliest ancestors.
Now, since I have offered you some explanation, what objectively-derived evidence do you have for your belief in God and Jesus being "the son of God"?
