Migration

In class today, I learned that North America was among one of the last regions colonized. Also, I did some more research about how the agricultural revolution occurred all over the globe at around the same time even though civilizations didn't have much contact with each other. The most interesting fact, in my opinion, is that we are beginning to have the ability to not only live longer than all of our ancestors, but actually defeat aging all together. We are learning the technology needed to prolong our aging indefinitely.
