Everyone Is Going Somewhere

There is an increasing agreement within the global scientific community that human beings (Homo Sapiens) originated in Africa and then spread out to the rest of the world in two or more distinct exoduses. Genetics has played a major role in confirming this idea (which really has been around since Darwin). Dr Spencer Wells is an American geneticist and anthropologist who has written a book titled Journey of Man: A Genetic Odyssey. National Geographic, in 2003, made the book into a documentary, which I recently watched. To me, the film was like cherry topping on a chocolate cake, since I just finished reading Jared Diamond's Guns Germs And Steel: The Fate Of Human Societies.

If we assume that this community of geneticists, paleontologists, evolutionary biologists and archaeologists is indeed correct then our history appears to be a rather short one (of about 60,000 years or 2000 generations) since the time we left Africa. With the rapid pace of technological innovation which is now underway it should not be long before we colonize the rest of the galaxy (or galaxies). Here we come.
