It was also interesting to find out that our language gene (FOXP2) could be a relatively recent gene. This gene could have started in ancient Neanderthals and was then passed on to the modern human. If that is so, evolution has won again!! But this is only a prediction, the FOXP2 gene could also have been developed in modern humans and passed on the Neanderthals, or maybe we are all wrong and FOXP2 is a very old gene.
This study helps us grasp a problem that has been laid out before scientists--what actually explains race. When explaining race by talking about environments experienced in the past, makes more sense than explaining race using 19th century ideas (racial relationships) which don't make much sense from the evolutionary point of view. The idea that there are genetic differences because of environments experienced in the past and demographic growth makes the most sense.
