Species trees may differ from gene trees — trees that rep resent the evolutionary history for individual genes throughout the genome — due to evolutionary processes such as hybridization\, horizontal gene tra nsfer\, and ancestral polymorphism. In this talk\, I will first describe mo dels for the relationship between gene trees and species trees\, focusing s pecifically on the case of ancestral polymorphism. I’ll then consider phylo genetically-based methods for studying biodiversity\, and demonstrate the i mportant distinction between genes trees and species trees. The impact of using gene trees vs. species trees will be examined with empirical data fro m several taxonomic groups\, ranging from yeast to mammals.\n\n \n\nHost: D r.
