BIOL 211 Lecture Notes - Lecture 19: Lactose Intolerance, Mammal, Mitosis
Document Summary
Change in population characteristics through decent with modification and natural selection. Being able to digest milk is something that many adults can not (lactose intolerant), but in. Europe and west africa, there is a trait that has been passed down and evolved to be able to digest milk. The ancient greeks had the concept that species were constant or fixed propoenets of a static or fixed creation believed: Fossils of organisms that currently don"t exist contradict the diea of a perfect creation. Evolution is the idea that species change through time. Closely associated with charles darwn, but others contributed and had similar ideas. Mendel"s work (mendel probably knew about darwin"s ideas) Individuals from one species did not breed with others. Came up with a classification system to put all species into it. Species are not fixed they change throughout time. The exponential growth of populations are limited (famine, disease) Eventually these will cross and create famine or conflict.
