Document Summary
Agonistic (sometimes can seem aggressive, threat gestures/signals) 1831 1836: darwin = naturalist on the hms beagle, the voyage, that circumnavigated the globe, included a surveying of the. Galapagos archipelago from apr. -oct. 1835: this was crucial to darwin formulating his theory of natural selection. Darwin"s finches: 7 finches = seek food (e. g. , seeds) on the ground or in low shrubs. Other 7 = tree finches, live primarily on insects: distinctive beaks. A history of the theory of evolution through natural selection. We remembered only darwin, but now we consider wallace. If you are a prey and are unsuccessful = death. If you are a predator and are unsuccessful = missed dinner. Responses of potential prey they can be quite complex. That is, natural selection is non-random; it is a probabilistic process: evolution is define as change in the gene frequencies of a population"s gene pool over time. Sources of genetic variation: gamete formation (meiosis)
