SUMMARY:Microcephaly genes &amp\; the evolution of primate brain size - St
 ephen Montgomery (Department of Zoology\, University of Cambridge)
DTSTART:20090604T120000Z

CONTACT:Dr James Kirkbride
DESCRIPTION:One of the most significant trends during primate evolution ha
 s been the expansion of the brain. Although this trend is most pronounced 
 in humans\, brain size has increased independently in all major groups of 
 primates. Recently genetic studies have identified a number of genes\, inc
 luding a class of genes called the microcephaly genes\, which are involved
  in brain size development and have evolved under positive selection along
  lineages leading to humans. However these studies were based on only a fe
 w primate species and the link to brain size is unconfirmed.\n\nThis talk 
 will explore whether the evolution of these genes and brain size are intim
 ately linked\, and whether this pattern is limited to human evolution.\n \
