    It lives in the ocean and eats squid. Why would it need thumbs, or lasers?

    "We lived in trees and ate fruit."

    And we still have the thumbs we evolved to help climb trees, and we still have the teeth we evolved to chew fruit. Frankie my man, you're not thinking any of this out before you spout off.

    Climate change. Jungle gave way to savanna so walking upright gave us the ability to survive.

    The climate has changed many times over the last 80,000,000 years. Does evolution only work in certain areas at certain times?

    The pressure to communicate via language, as living in groups helped humans thrived.

    You know, you are asking childish questions about evolution that you could go look up yourself

    No, not at all. I'm asking why this mysterious force of "Evolution" is so selective

    It's not. In one species, smaller size may be favored. In another, larger size.
