Document Summary
*what is a hypothesis: explanation of an observation/phenomenon, testable, needs a mechanism, ex. Atlantic salmon have more salmon lice in summer because salmon lice grow more rapidly in warm water. What does it mean: difference between ediacaran (pre-cambrian) and cambrian fauna, darwin"s voyage and other famous discoverers. Informative characters when more than 1 species has the derived character state (synapomorphies: derived traits are used to form phylogenies, non-informative characters when only 1 species has the derived character state (apomorphies, ex. Gave an activity to draw a tree based off of given characteristics. Population genetics: p + q = 1. Breeder"s equation: predicts evolutionary change in a trait (ie. beak depth, r = h2s, this equation can be rearranged, s and r have equations too, s = xbars xbarp1, r = xbarp2 xbarp1. Some concepts for short answers: modern synthesis, darwin"s theory how it lead to and is different from the modern synthesis, population genetics calculation questions, quantitative genetics calculation questions.
