Schizophrenia arose only after Neanderthals?

From ScienceDaily:

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. Paper. (public access) – Saurabh Srinivasan, Francesco Bettella, Morten Mattingsdal, Yunpeng Wang, Aree Witoelar, Andrew J. Schork, Wesley K. Thompson, Verena Zuber, Bendik S. Winsvold, John-Anker Zwart, David A. Collier, Rahul S. Desikan, Ingrid Melle, Thomas Werge, Anders M. Dale, Srdjan Djurovic, Ole A. Andreassen. Genetic Markers of Human Evolution Are Enriched in Schizophrenia. Biological Psychiatry, 2016; 80 (4): 284 DOI: 10.1016/j.biopsych.2015.10.009

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?)

    I can telkl this is a porly done research paper.
    Saying this illness comes from evolutions influence on the brain is just irresponsible (intellectually) research.
    This illness can easily be seen in a spectrum of mental problems. nothing special.
    I think its just triggering problems with the memory and so a simple failure. Not an innate genetic problem.
