Document Summary
The columbian exchange: exchange of food, people, genetics, etc. from the americas to europe, vice versa, wheat, cattle, etc came to americas, changed the diets of several, epidemic diseases came to the americas. Study of non human primates fossil and living apes, monkeys and prosimians. Usually ground monkeys. (chimps and apes: zoological taxonomy. Assignment of organisms to categories (taxa) according to their relationship and resemblance. Humans and apes belong to the hominoids. Superfamily (humans and primates) hominoid/hominoidea: family, tribe, genus, species, organisms should be assigned to the same taxon or the basis of homologies. Homologies: similarities organisms jointly inherited from a common ancestor. Analogies: similar trairs can arise if species experience similar selective forces and adapt to them in similar ways. Bat development vs bird development: similar in structure but process is different. Convergent evolution: process by which analogies are produced. Anthropoids: old world and new world monkeys, apes, chimps, orangutans, primate tendancies.
