Our History, Our Future
The common ancestor that we shared with chimpanzees about six million years ago was much more like modern chimps than us. In our lineage, the hominids, so many changes occurred: bipedalism, substantially larger brains, tool use, language, and so on. The genetic bases of these important transitional changes remain murky at best. What genetics has shown us is that we are one species, somewhat lacking in genetic variation, and having only slight differences among different populations. Genetic studies have also shown that disease and other factors continue to substantially affect our evolutionary trajectory.
