Summary Introduction
To describe: The way in which horizontal gene transfer scrambles the concept of monophyletic groups.
Introduction: The phenomenon of horizontal gene transfer is described as the process in which an organism incorporates the genetic material of another organism in its genome. This process is generally observed in lower prokaryotes.

- The biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical.
