From June 11th
As humans, we are the lucky beneficiaries of three biological developments that greatly contribute to our long-term survivability. The first one is the structure of our jaw which is conducive to eating meat and taking in proteins that non-meat-eating mammals don’t get. That’s the only one of the three that’s irrelevant to the discussion.
The second of the top three biological developments that contribute to our long-term survivability is our cerebral cortex. The cerebral cortex is the outer-most layer of the brain, and is principally responsible for conceptual thought. Because of our cerebral cortex, we can imagine things that we cannot see. We can conceive of stuff we did not experience.
The third biological development that contributes to our long-term survivability is our opposable thumbs. Our opposable thumbs are pretty useful. They gave us the ability to carry things and to share with others. They gave us the ability to use and manipulate tools.
