Lecture 14 - Species and Speciation

Lecture 14 - Species and Speciation

This video was recorded at EEB 122 - Principles of Evolution, Ecology and Behavior. Speciation is the process through which species diverge from each other and/or from a common ancestor. There are several definitions of species, most of which focus on reproductive isolation and/or phylogenetic similarities. This can cause some controversy. Speciation can result from geographical separation or ecological specialization. There are stages of speciation in which organisms cluster first into distinct populations before finally becoming different species. Reading assignment: Stearns, Stephen C. and Rolf Hoekstra.
