Chapter 26.5, Problem 1CC
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.

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. When in the lab they mated successfully, and the offspring of that mating also mated…arrow_forward

- What is the last universal common ancestor (LUCA), and what does that mean? What is a phylogenetic event horizon?arrow_forwardAn analysis of the phylogeny of mutualistic and free-living fungi, as well as the rates of nucleotide substitutions in selected ribosomal RNA regions, was conducted with a view to determining how coevolution can drive changes in the heritable traits of a species. Which of the following is NOT the expected outcome of the study? A. There was a faster rate of molecular evolution occuring among free-living fungal species compared to lichens. B. Fungi coevolving with algae in lichens featured higher rates of nucleotide substitutions. C. Higher rates of nucleotide substitution in mutualistic fungi were widespread across many sections of the genome. D. The transition to mutualism accelerated the rate of molecular evolution for fungal species.arrow_forwardWhat notion is common to the morphologicall species concept, the biological species concept and the phylogenetic species concept?arrow_forward
