NSF Web Site Press Release 11-041 Homoplasy: A Good Thread to Pull to Understand the Evolutionary Ball of Yarn Studying the many potential reasons why the same trait has independently evolved in different species (homoplasy) can improve our understanding of the genetic, developmental and evolutionary relationships among species An evolutionary tree must be created to determine why two species share the same trait. Credit and Larger Version February 24, 2011 With the genetics of so many organisms that have different traits yet to study, and with the techniques for gathering full sets of genetic information from organisms rapidly evolving, the "forest" of evolution can be easily lost to the "trees" of each individual case and detail. A review paper published this week in Science by David Wake, Marvalee Wake and Chelsea Specht, all currently National Science Foundation grantees, suggests that studying examples of homoplasy can help scientists analyze the overwhelming deluge of genetic data and information that is currently being generated. For example, studying situations where a derived trait surfaces in two lineages that
