Document Summary
Teams collected fossils (physical remains of some or all of once-living organisms that have become mineralized by replacing organic materials with inorganic materials. Darwin in 1831, voyage around world on the beagle. Species: group of related organisms that can interbreed and produce fertile, viable offspring. Darwin was interested with variation between species and within species. Islands varied by habitat (specific area of natural environment) even within the same island. Physical variation is due to adaptions (changes in physical structure, behavior, or function that let organism survive and reproduce better in a given environment) Natural selection: the process by which organisms adapt to the environment, making some traits and the individuals carrying those traits more fit than others, which drives evolution. Adaptive radiation: the diversification of an ancestral group of organisms into new forms that have adapted to certain environmental niches. Darwin drew from five scientific disciplines: geology, paleontology, taxonomy, demography, and evolutionary biology.
