Introduction to Anthropology Chapter 4 Genetics and Evolution Creationism: biological traits originated at creation – immutable Scientists’ predictions for creation: o Ussher and Lightfoot – October 23, 4004 B.C. at 9 am o Charles Lyell – (geologist) earth is millions of years old o Carolus Linnaeus – classification of plants and animals o Charles Darwin and Alfred Wallace – theory of evolution by Natural Selection (nature selects the most fit individuals to survive) o Gregor Mendel – (1856) Australian monk that experiments with pea plants, inferred the main principles of genetics Some traits dominate others (tall dominates short) 7 traits: Smooth vs. wrinkled seeds Yellow vs. green seed interior Gray vs. white seed coat Inflated vs. pinched pod Green vs. yellow pod Axial vs. terminal pod Tall vs. short stem Law of independent assortment: traits are on different chromosomes Factors are now known as alleles, which are located on the chromosomes Dominant Recessive Genotype: two alleles for each trait Phenotype: appearance of the organism (physical traits) Punnet squares o Mitosis – replication of DNA in somatic cells (body cells), produces two identical daughter cells o Meiosis – replication of sex cells o Mitochondrial DNA – given to the zygote from the mother Four ideas of Evolution o Natural Selection – survival of the fittest, surviving genes will have greater frequency in the next generation. Acts directly on phenotype and indirectly from gene frequency EX: sickle cell Sexual selection – (feathers of a peacock) peacocks find large plumage attractive, and the bigger the plumage the better Artificial selection – process by which humans select a specific phenotype in domesticate plants and animals to breed that certain phenotype o Mutation – produces variation, only mutations in sex cells are passed on, happen by chance o Random Genetic Drift – Founder’s Effect, change in gene frequency due to chance, can also increase gene frequency Old Order Amish – 200 members, 39 diseases Hutterites – 443 members, 25 disorders Mormons – 2000 members and more, same as any European population o Gene Flow – direct or indirect breeding between populations Speciation – no gene flow
