BIOL-4717EL Lecture Notes - Lecture 1: Jane Goodall, Photoperiodism, Comparative Psychology
Document Summary
European development, you have to look at things in a particular way. Based on field study, jane goodall spent 1000 of hours watching. Has many variables, (social interactions like lights, temperature, predators) No or little statistics because of too many variables. Whatever the stimulus is, it triggers the animals behavior. Controlled conditions (light, photo periods, temperature, humidity etc) Problem of interpreting animal behavior in a human context not interpreting it in our own behavior. Wynn- huxley, - group selection, groups behave in a way to maximize. Many mutations in fruit flies vgvg, two recessive alleles- affects wing development. Y1y- two recessive alleles- affects pleiotropism (affects many traits) Compare reproductive success of yellow vs. normal males. Why- yy had slower wing beats per second, wings produce sound, when male produces wrong song. Peck material on beak to nest: roseocollis, puts nesting material into tail feathers. Created hybrids- which genetic trait is going to be inherited by hybrids.
