I think we can agree that if even you want to distance yourself from that trope, you must realize how asinine it really is.
I can think of several terms here that you're going to have to be more specific about, before you can graduate from "believing" in something to "understanding" it.
Those three terms are ape, man, and "the wild."
Let's start with "the wild."
You said something good here: "I believe the animal best suited to its environment survives and breeds and passes on its traits to the next generation and change occurs that way."
Now, the next step is to realize that an animal's environment is in a constant state of change... and what was "suitable" a year ago can quickly become a death sentence.
Now, what happens to a species if its environment changes faster than they can pass on their traits?
Answer: it goes extinct.
UNLESS, of all the possible traits that an animal can develop, there was one that gave the animal the ability to adapt to changing conditions in its environment in its current generation?
Well, there is -- and it so happens that a long time ago, a group of ape-like ancestors developed this trait, and they've been running with it ever since:
Intelligence.
You think apes are better suited for living in "the wild" than humans? Then help me out here:
Gorillas: Critically endangered
Chimpanzees: Endangered
Orangutans: Critically endangered
Bonobos: Endangered
Humans: Doing just fine; thanks for asking.
And why are the four (other) types of great apes on the brink? It comes down to three things: hunting, habitat loss, and habitat fragmentation.
... and guess who's responsible for all three?
"The wild" is a mythical place these days -- the only reason these or any other animals even have an environment is because we allow them to have one...
... and we're not all on the same page about allowing them, are we?
