ANTD22H3 Lecture Notes - Lecture 1: Coopetition, Sexual Selection, Overproduction
Document Summary
Adaptation: micro-changes in gene frequencies from generation to generation. Evolution: changes in gene frequency build up, leading to evolutionary product. Overproduction- lot of offspring born that never made to adulthood; lot of coopetition. Inheritance- inheritance of this variation to make it to adulthood; hence not everyone"s genetic variation gets passed on. Those who are most well-suited to the environment; whoever with the variant that allows them to thrive in that environment/ time. Disadvantageous traits get passed on on lower frequencies. The more offspring= more genes passed on= higher reproductive success. Not only about reproductive success, because you share genes with your relatives, there"s still copies of your genes passed onto the next generations (your fitness) Both morphological and behavioral traits can be passed on- if certain behaviors help with reproductive success, then they do get passed on. If a trait hinders your reproductive success, it gets passed on less frequently.
