Document Summary
Zoo*2700 study questions winter 2015 week 1 (lectures. 1. (1) variation within the population. (2) genes are heritable. (3) overproduction of offspring. (4) Since there is competition, one may give an advantage over the other (perhaps camouflage, so predated less). Linnaean levels de-emphasized: monophyletic taxon includes all the descendants of a single immediate ancestor. Paraphyletic taxon group that includes some, but not all of the descendants of a stem species. Some prokaryotes could not adapt (hence still used glycolysis) ii others were able to become aerobic iii possibility that an anaerobic cell swallowed an aerobic cell, and a symbiosis relationship developed. Internal support cytoskeleton: actin and microtubules, trypanosomes are kinetoplastids, african sleeping sickness (tsetse fly, chaga"s disease (blood sucking bugs) i ii. Fever, swelling, pain, heart failure, and death: choanoflagellates synapomorphy with primitive monociliated animals: single flagellum that bears a bilateral vane of mastigoneme-like filaments and is surrounded by a cylindrical collar of microvilli.
