BIOL 3040 Lecture Notes - Lecture 1: Guppy, Evolutionary Arms Race, Gene Duplication
Document Summary
Depending on the mouse"s coat color, a mouse could be more or less susceptible to hunters if they did not blend in with their environment. Low predation = less but bigger guppies: describe reznick"s experiments on guppy populations and explain how the data supports the idea of tradeoffs in life history strategies, see above answer. 3. 4 natural selection in the laboratory: describe the lenski"s long-term evolution experiment, what traits changed over time in the population. Lenski"s evolution experiment involved transferring e. coli for 3000+ days in 12 different lines and periodically freezing some samples in -80 degree c. 3. 5 constraints on what natural selection can achieve: elaborate on three reasons why there are limitations on what natural selection can achieve. Scaling relationships (need correct structures to support large weights; legs get: physical constraints thicker the larger an animal gets, evolutionary arms race.
