Document Summary
Natural selection: travel: 1831-1836, return to england (darwin): 1836; age 27, after the travel (i. e. after 1836) The main mechanism: natural selection: 1844. Dear mr. darwin (from wallace to darwin) On the tendency of varieties to depart indefinitely from the original type. Wallace could not have made a better short abstract of my own work! . Both papers (darwin"s & wallace"s) were presented publicly. Biodiversity: dynamic over time, not static. Common ancestry: a relatedness among species. Natural selection: darwin"s 4 postulates, ernst mayr. The existence of shared ancestry between in different species: a pair of structures, genes. Selected traits will increase in frequency in the population on next generations causing evolution. Natural selection (ernst mayr: 1. (overproduction) for all species, population sizes would increase exponentially if all individuals born would survive to breed, 2. (finite resources) resources (food, space, nest sites ) are finite leading to.
