The skulls of humans from the Pleistocene epoch (roughly 2.6 million to 12,000 years ago) show an unusually high occurrence of genetic abnormalities like this skull-hole deformity, the researchers found. Since we are all humans and all share a common ancestor somewhere down the line, we all have some degree of inbreeding. That might skew the researchers estimate of how prevalent inbreeding is in the larger population. In a small population, matings between relatives are common.

People whose parents may have been third- or fourth-degree relatives, for example, werent looked at in this study, so the researchers cant say anything about the effects of milder inbreeding. Here are just a few of the genetic mutations that come from incest, as well as the expression of recessive genes you might never see otherwise. This has led to them sometimes being called "the ostrich people." This can lead to infections and even death. Inbreeding also increases the risk of disorders caused by recessive genes.
