So you think gorilla hands are evidence of apes to humans. My explaining the differences did not dissuade you.
"Darwin contended that in nature the weaker varieties of animals and plants are ‘killed off’ by the stronger varieties due to their better ability to compete for food or withstand environmental change. This is what is referred to today as survival of the fittest or natural selection."
...
"Natural selection acts as a breeder and eliminates all the dark haired bears from the Artic environment; we are left with only white haired bears. Still, we are left with bears and only bears. No new species, no new animals. Bears are still bears and the white haired varieties are called polar bears, which apart from the color of their hair are almost identical to their brown haired brethren."
Then, please explain why gorillas, others apes and monkeys are still living? We have established a history of common ancestors die off with natural selection and survival of the fittest.
