 eley\n\nTitle:  Promiscuity in the Paleozoic: looking back in time with ge
 nomics\n\nHost:  Veit Elser and Chris Myers\n\nAbstract:  As products of e
 volution\, genomes document the history of life in a way that complements 
 the fossil record. Although this genomic record is partially obscured by t
 he accumulation of mutations\, we can nevertheless look back across hundre
 ds of millions of years by focusing on genomic features that are conserved
  or slowly evolving. In this talk we introduce the basic principles of com
 parative genomics and use them to trace the elusive ancient events that tr
 ansformed our invertebrate ancestors into early vertebrates. These events\
 , which occurred nearly half a billion years ago\, include interspecific h
 ybridization and genome doubling\, which are revealed by a kind of symmetr
 y breaking. Analysis of the complex history of vertebrate genomes allows u
 s to fill a gap in the fossil record\, and points to an understanding of e
 ven more ancient events in the history of animals.
