out Natural selection is why we are different from the rest of animals.
Now firstly, I just want to say we did not evolve from monkeys, but we had a common ancestor. Our progressive evolution took millions and millions of years. We likely developed they way we didn't with our brains as a means of survival, in terms of physical strength and defense humans have very little.
It would have started with very small traits in which we share with lemurs, old world monkey, new world monkeys and great apes, first the development of binocular vision, the development of an opposible thumb, and then development of the frontal lobe which is involved with higher thinking.
Remember how much evolution occured between Homo Erectus- Homo Sapiens. That is just the tip of the ice berg.
We developed not because we were better than other species, more that it was the only way in which we could survive.
