Basically, the gorillas are descended from the ancient African apes that became cows, eating little else but vegetation and breeding in harems.
Humans are derived from that ancient African apes that became wolves, hunting large prey species with our refined tools (the result of our unusually large brains) and (usually) breeding in social units that were based upon a pair bond.
Both gorilla species (Eastern and Western) are quite threatened with extinction. The mountain gorilla subspecies of the Eastern gorilla is critically endangered.
Humans have taken over the world, and we like to think that our technology removes us from nature. And it does to certain extent. But we are still part of nature. It is a mere delusion of technological advancement that we have removed ourselves from it entirely.
As an aside: Isn’t it hard to deny evolution when you look at a gorilla’s eyes?
