SUMMARY:Do Neandertal and Modern Human Neanderthal craniofacial difference
 s reflect contrasting sexual selection for vocal pitch? - Professor Stanle
 y Ambrose ( University of Illinois Urbana-Champaign)

CONTACT:Dr Mark Dyble
DESCRIPTION:Enhanced sexual dimorphism in great ape craniofacial dimension
 s is associated with intergroup aggression and mate competition\, and with
  high testosterone levels. Testosterone influences suprapharyngeal vocal t
 ract (SVT) length and vocal pitch. Differences in epigenetic regulation of
  genes that affect vocal tract and facial anatomy between neanderthal and 
 modern human ancient DNA suggests down-regulation of SVT genes can account
  for facial reduction in modern humans. Epigenetics supports the hypothesi
 s that sexual selection on vocal pitch may explain many differences betwee
 n neanderthal and modern human cranio-facial morphology.
