DESCRIPTION:Speaker: Charles Nunn\nhosted by Sylvia Cremer\nAbstract: A fam
 ous sleep biologist once noted\, “If sleep does not serve an absolute vi
 tal function\, then it is the biggest mistake the evolutionary process eve
 r made.”  Indeed\, over evolutionary time\, sleep has become integrated
  with almost every dimension of biological function in mammals\, including
  growth\, cognition\, immunity\, and metabolism.  Research across mammali
 an species has revealed how ecological factors\, including sociality and p
 redation\, influence sleep characteristics.  More recently\, we have docu
 mented how many of these same selective forces have shaped the evolution o
 f human sleep relative to other primates\, resulting in a marked decline i
 n total sleep time and an increase in the proportion of REM sleep along th
 e human lineage.  I will present these evolutionary findings and discuss 
 the follow-up research we have conducted in Madagascar and Tanzania to bet
 ter understand the ecology of human sleep.  Collectively\, our findings s
 uggest that risks and opportunity costs have shaped human sleep in terms o
 f duration\, quality\, and social patterning.  Perceptions of threat in o
 ur increasingly urban and stressful world are likely triggering many of th
 ese same effects\, potentially leading to sleep disparities that drive hea
 lth disparities in marginalized populations.
