There are many diseases for instance that one race will get (either at all or predominantly) by one race over another is far more common than anyone is allowed to talk about (with out being deemed as racist).

While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago.
Now, after studying ancient rocks in southern West Greenland, one team of researchers says that modern plate tectonics, with its subduction zones, spreading centers, earthquakes and all the other features we're familiar with, probably started about 3.2 billion years ago (the Earth is about 4.6 billion years old). Before that, a much different set of processes shaped the Earth's surface, the researchers say.
