Human evolution running at breakneck speed

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.
