Document Summary
Constant rate of evolutionary time, phylogenetic tree, a potential measure of distance that can give you a commonality of the split. Evolutionary time frame, steady change that can be used to figure when there are splits in lineages. Strep- small, solitary, lemurs, more primitive/further back. Hap- new/old monkeys, apes, bigger, larger brains, more social, no specialized vision, or reliance on smell. Know what makes apes different from monkeys. Crossing over is during meiosis (split of chromosomes) this can cause variation in offspring. Locus- where the gene is located on the chromosome. Giving a benefit and you suffer the cost. Benefits the group- group selection- can"t work tho you"d end up losing the altruistic act. Kin selection- others/children have your genetic material so they have your genes to continue. Relationship to others- . 5 for parents, . 125 for cousins, . 25 for grandparents etc . C= the fitness cost to the individual.
