"Fossils suggest the inbreeding took its toll, says Erik Trinkaus of Washington University in St Louis, Missouri. Those he has studied have a range of deformities, many of which are rare in modern humans. He thinks such deformities were once much more common (PLoS ONE,
doi.org/p6r)."

"Some of the deformities appear to be inherited, and others are due to genetic factors, the paper says. Paired with the high rates of such deformities, it leads Trinkaus to what probably shouldn’t be a shocking conclusion: Inbreeding was likely fairly common among early humans.
"Early humans most likely lived in small groups spread far from each other, and the geographical limitations of their lives would have made reproducing with relatives inevitable. Additional evidence in favor comes from the fact that some of the specimens with similar deformities were found in the same places, implying that they were related."
