WebBig Picture. Darwin’s voyage on the HMS Beagle to visit the Galápagos Islands in 1831 and his resulting theory of evolution proved to play an instrumental role in our understanding of the organisms on earth today, despite the extreme controversy of his theory at the time. He introduced the idea of natural selection, in which the animals that were best fit to the … WebUnderstanding: Natural selection can only occur if there is variation among members of the same species. Natural selection is a process of evolution in which organisms better adapted to their environment tend to survive and produce more offspring. Outline the process of evolution through natural selection.

WebNatural selection, or “survival of the fittest,” is the more prolific reproduction of individuals with favorable traits that survive environmental change because of those traits. This leads to evolutionary change. WebToday, natural selection forms the basis for our understanding of how species change over time. Natural selection may act to change a trait in many different ways. When selection pressures favor the average form of the trait, selection is said to be stabilizing. Directional selection occurs when selection pressures favor one extreme of the ...
