Modern humans have been on the planet for about 200,000 years. Civilization is only about 6,000 years old. We are still very much a product of that 194,000 years. We’ve adapted to our new surroundings surprisingly well given how rapidly our environment continues to change, yet we often and inevitably fail ourselves—or at least the version of ourselves we’re trying to be –because we are still subject to crushing biological law that has been part of our genetic makeup since before we were even the species we know ourselves to be today.
