Office hours: wed. 1:30-3:00 1089 sciences lab building (aka the blc) Office hours: monday 12:10-1:30 pm, 1089 sciences lab building (aka the blc) #29 for practice questions for midterm 1: answer is a and c (c is vague but applicable) Heritable and survival enhancing traits relative to other members of pop. will increase in frequency from gen-to-gen, so long as particular selective regime persists. Lamarckian transformational evolution = use and accentuation of traits. Darwinian variational evolution = natural selection, cross breeding. Adaptation (noun) - trait that increases organism"s survival or reproductive success. Adaptation (verb) - refers to process which a beneficial trait spreads in population. We measure increased survival / reproduction as fitness: # of offsprings that survive and reproduce relative fitness is critical as traits are measured by their frequencies.
