RT Journal Article T1 Williams Syndrome, Human Self-Domestication, and Language Evolution A1 Niego, Amy A1 Benítez Burraco, Antonio AB Language evolution resulted from changes in our biology, behavior, and culture. Onesource of these changes might be human self-domestication. Williams syndrome(WS) is a clinical condition with a clearly defined genetic basis which results in adistinctive behavioral and cognitive profile, including enhanced sociability. In this paperwe show evidence that the WS phenotype can be satisfactorily construed as ahyper-domesticated human phenotype, plausibly resulting from the effect of the WShemideletion on selected candidates for domestication and neural crest (NC) function.Specifically, we show that genes involved in animal domestication and NC developmentand function are significantly dysregulated in the blood of subjects with WS. We alsodiscuss the consequences of this link between domestication and WS for our currentunderstanding of language evolution.
