Makes me wonder how human activity is evolving our very own genetic pool. Examples: competition vs cooperation, male vs female height, our immune system. We have long had a culture where men prefer mates that are shorter than them, and women prefer mates that are taller. This results in constant pressure on the pool resulting in men being on average taller than women. Will this change over time as we outgrow this rather primitive preference? (Sadly, even many feminist women have clung to this preference.) Not all species "prefer" that the male is bigger or stronger than the female. An obvious one is our reliance on modern medical technology, and drugs in particular. Are our bodies becoming less able to fend off disease? The most important one for me is the balance between those genes that give us our selfishness and those that give us empathy and love. What impact does an ever more individualistic culture and an economic system that defines selfishness as a virtue have on our gene pool?
