BIOLOGY 171 Study Guide - Final Guide: Interspecific Competition, Character Displacement, Exponential Growth
Document Summary
Divergences between chimp and human is between 5-7 million years ago. More than one species being produced in more than 1 million years. Stockey hominins with robust teeth and jaws and grass/seed diet. How do biologists study evolution of humans. Genome wide association studies (gwas) usings snps to detect selection. To find take the final population size over the initial population size. When birth and immigration rate are at the highest. Death and emigration rate are at the lowest. Population density on the x axis vs time on the x axis. Maximum population size that the environment can sustain given the food, water, habitat, and other resources available in the environment. Only intraspecific competition regulates the population at k. Competition among individuals of the same species. Many things can regulate population size at points other than k. Evolutionary change in resources by coexisting species. Morphological change in coexisting species to use different resources.
