Document Summary

Evolution: how living things change over time: natural selection. The process of reproduction causes variability, one of two ingredients for natural selection. Two primary resources of variability: mutation: random mistakes in dna replication. Evolution: the concept that different species are descended from common ancestors but have evolved over time, acquiring different genetic characteristics as a function of different environmental demands. Natural selection: the process by which certain attributes are more successful in a particular environment and therefore become more represented in future generations. Naturalistic fallacy: a bias toward believing that biological adaptations are inherently good or desirable. The second ingredient for natural selection is competition. Variability and competition in particular environments determine which genes are passed along. Creatures that possess attribute to improve their quality of life and survival and more successful in passing genes to the next generation; these attributes are called adaptations.
