And has been doing so for the past 5,000 years. Humans today are more different from humans of 5,000 years ago than those humans were from the last of the Neanderthals 30,000 years ago.
Among the main driving forces? The explosion in human population and the invention of agriculture. The main changes caused include digestive abilities, per the rise of agriculture, and resistance to disease, per the density growth in human population, which largely was an Old World phenomenon, as the disease non-resistant pre-Columbian Americans were to learn.
Global warming, increased human migration and other issues will certainly get a new look in light of this.
This is a slice of my philosophical, lay scientific, musical, religious skepticism, and poetic musings. (All poems are my own.) The science and philosophy side meet in my study of cognitive philosophy; Dan Dennett was the first serious influence on me, but I've moved beyond him. The poems are somewhat related, as many are on philosophical or psychological themes. That includes existentialism and questions of selfhood, death, and more. Nature and other poems will also show up here on occasion.
