PSYC 208 Chapter Notes - Chapter 1: Genomic Imprinting, Hominidae, Chromosome
Document Summary
Misconceptions: species do not outcompete other species, individuals outcompete other individuals. Evolution: change over time in organic structure or behaviour (gene frequency) Structural similarities among species (ex: mammals have same basic body plant) Embryological development (embryos of many species look similar until later development) Dna (basic building blocks of dna are identical; thymine, cytosine, guanine, adenine; suggests common ancestors) Naturalist on the beagle (1831 1836) Alfred russell wallace: co-discoverer of evolution by natural selection, officially recanted his theory. Thomas henry huxley: read darwin"s theory, became darwin"s bulldog. Variation: individual differences between members in a species. Inheritance: heritable traits are passed along generations (not acquired traits) Selection: some entity is selecting individuals to reproduce: fact: organisms exist in larger than their environment can sustain. Mutation: added later as principle of evolution, darwin didn"t know about it. Speciation: creation of new species from old species. Adaptation: how organisms change to adapt to its environment.
