DESCRIPTION:The Cambrian radiation of animals started ca. 550 million year
 s ago\, and was terminated by the first mass extinction of the Phanerozoic
 . The unicellular ancestors of animals possessed similar genes to those im
 plicated in the development of animal traits\, so why did it take so long 
 for animals to appear and become ecologically dominant? I will explore the
  role of oxygen in creating habitable space for animals to diversify\, and
  show that this radiation was not linear\, but cyclical.
