Document Summary
This chapter: considering biological basis/ evolution to understand behaviour. For thousands of years, people knew that they could cross-breed animals to get the traits that they want in the animals (ex. retriever dogs for hunting, varieties of pigeons were produced through artificial selection like blue grizzle frillback, Mutation showed up and people bred that mutation in the species to produce a stable line with that mutation as a desirable trait. Charles darwin formulized the theory of evolution & natural selection. Darwin published the origin of species (1859) 3 main ideas: heredity, variability, & natural selection. Variability= characteristics across species -> in homo sapiens: eye colour, hair colour, height, personality, weight, intelligence. Natural selection= survival of the fittest (most successful in competition for resources) About me and my genes, not about individuals. Those who reproduce are more successful in the long run in an evolutionary sense.
