Unformatted text preview: Anthro 101 – Final Review The process of fossilization requires: a. Burial b. Trampling – may occur c. Replacement of organic material d. All of the above e. A & C only Dryopithecus may be ancestral to: a. Lemurs andlorises b. African apes and humans c. Orangutans and hylobatids d. Only gorillas e. Chimpanzees and humans Genetic drift: a. Is a random change in allele frequencies b. Has the greatest effect on small populations c. Commonly occurs during bottlenecks (founder effect) – migration from Northern Asia into the Americas; ended up populating all of north and south America. d. All of these e. A & B only • O type blood is the most common blood type in the Americas Anthropology in Canada developed from studies by: a. Evolutionary biologists b. Extraterrestrials c. Natural historians – in Europe d. Missionaries e. None of the above All of the following traits are present on all primates except: a. Grasping hands b. Clavicles c. Postorbital plates (lemurs) d. Stereoscopic vision e. Rotating forearms Hylobatids have what type of social organization? a. Multi-male, multi-female – ex. Baboons, chimpanzees b. One-female, multi-male – ex. Humans in Northern Asia (polyandry in Mongolia) c. One-male, multi-female – ex. Gorillas d. Semi-solitary – ex. Orangutans e. Pair-bonded • Recombination - exchanges of genes on paired chromosomes during meiosis • Gene Flow will prevent speciation if the populations come into contact before sufficient evolutionary change has occurred • Allopatric speciation is the process of evolving two species from one through geographic isolation, divergence, and reproductive isolation – other types: Biological Species Concept, Main Recognition Concept, Morphology (useful in fossils) • Adaptive Radiation is the evolutionary diversification of one species into many species through the adaptation into several distinct ecological niches • Biostratographic Dating is a method of dating a site by matching its fauna assemblage to other sites that have been well-dated – AKA Faunal Correlation (used in South Africa to give an estimate of dating because they don’t have definite ways to date absolutely as opposed to East Africa where you can date site more precisely using Absolute Dating ex. Potassium – gives you an exact number) • An individual that has 2 different alleles (Tt) at the same location on paired choromosomes (genetic loci) will have the genotype Heterozygous • Name one type of mutation – Point, Insetion, Deletion, Inversion, Sickle Cell Anemia, Down Syndrome *** Look at the tree we had to know for the midterm – will be on the final *** Look at the blue boxes in the textbooks – very helpful *** Hylobatids – brachiation (only ones), pair-bonded, very small Acheulean Tools: a. Are unifacial b. Are cores c. Are made through pressure flaking - blades d. Do not have a uniform shape e. Are found from 2 to 1 million years ago Which species was alive at the same time as.//…………….!?!?!?Which species was alive at the same time as....
