Summary of Darwin's Theory of Evolution:
A species is a population of organisms that interbreeds and has fertile offspring.
Living organisms have descended with modifications from species that lived before them.
Natural selection explains how this evolution has happened:
More organisms are produced than can survive because of limited resources.
Organisms struggle for the necessities of life; there is competition for resources.
Individuals within a population vary in their traits; some of these traits are heritable -- passed on to offspring.
Some variants are better adapted to survive and reproduce under local conditions than others.
Better-adapted individuals (the "fit enough") are more likely to survive and reproduce, thereby passing on copies of their genes to the next generation.
Species whose individuals are best adapted survive; others become extinct.
●Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection.
●Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.
●The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
●Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.
