Show for Jan 13, 2013. Human Evolution Marches On?
People love to trip out on the subject of future human evolution, usually conjuring some form of twinkly transcendence (a seraphic super-race) or dystopian degeneracy (machine-dependent dullards enfeebled by our own technology). But those stories owe more to wishful thinking or baseless anxiety than to actual evolutionary theory. I decided to forgo the fantasizing and explore the science itself: the forces that shaped our species and that are still at work, however subtly, today. Evolutionary biologist Barry Sinervo joined me to explain the fundamentals and offer some educated guesses on what comes next.
Barry has been on the 7th Avenue Project twice before, discussing lizard evolution and game theory here and a major new study of climate-related extinctions here.
