We (humans) ARE one of the ape cpecie who lived in Africa a million years ageo. How can we, that ape, stay the same over million year?

There were about 10 branches of our specie, some of them made it not only from tree to the ground, but even out of Africa about 10^5 years ago and reached: near (and then far)Asia about 6x10^4 years ago, Australia about 5x10^4 years ago, cold Europe about 4x10^4 years ago and finally very cold North America (via frozen Bering trait) about 15x10^3 years ago, and then South America about 10x10^3 years ago.

Plenty of antropological and genetical evidences for that.

By the way, genetic difference between caucasian (european) and asian race is 0.1%, between european and black - about 0.2%, between european and chimpansee 1.4%, european and gorilla - 2%, european and orangutang - 3% and so on and so on.

So, we all (humans which are apes in progress, and all other animals which are animals in progress) are TRANSITION specie on the tree of evolution.

Take a look on an ordinary tree - which branch is the transitional branch to the next branch?
