Schizophrenia poses an evolutionary enigma. The disorder has existed throughout recorded human history and persists despite its severe effects on thought and behavior, and its reduced rates of producing offspring. A new study may help explain why-comparing genetic information of Neanderthals to modern humans, the researchers found evidence for an association between genetic risk for schizophrenia and markers of human evolution.…
“Our findings suggest that schizophrenia vulnerability rose after the divergence of modern humans from Neanderthals,” said Andreassen, “and thus support the hypothesis that schizophrenia is a by-product of the complex evolution of the human brain.” More.

Even for the August news dead zone this is reaching. W don’t know that Neanderthals didn’t have schizophrenia or even that racoons don’t have it. (But who would know or care?)
