Aug 6, 2020 · What is the principal theory of how evolution works? Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.

The cell theory states that all living things are made up of cells, and living cells always come from other living cells. The gene theory states that the characteristics of living things are controlled by genes. Homeostasis is maintaining a constant internal environment. Evolution is a change in species over time.

Though our understanding of evolution has greatly increased since Darwin’s time (since evolution is a theory in the scientific sense), these basic principles remain fundamental components of evolutionary biology. Despite their simplicity, it took a significant amount of work over several years for Darwin to piece these ideas together …

Charles Darwin was the first person to give the world strong reasons for believing that plants and animals had evolved.Variation. In evolution, the fate of an individual depends on which features it has. Each human, for example, inherits a unique combination of thousands of different features, such as eye color, blood type and sensitivity to certain tastes. Some variants, or versions of a feature, may help an organism to survive. Others may be harmful. According to the evolutionary theory on which the conclusions about relationships rely, everything people do is designed to promote childbearing. Most people think this is an undesirable view of relationships. Yet, it does make some sense.

Evolution works through a process known as natural selection. Natural selection makes it more likely for the best-adapted individuals to survive and reproduce.

Evolution: Fact and Theory. A student measures a hominid skull. Scientific understanding requires both facts and theories that can explain those facts in a coherent manner. Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth.

Darwinism. Charles Darwin in 1868. Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.

In his major book published in 1944, Tempo and Mode in Evolution, Simpson divided evolutionary change into "tempo" (rates of change) and "mode" (manner or mechanism of change) with tempo a regulating factor of mode. Simpson's primary contention was that the fossil record clearly and inarguably supports Darwin's theory of natural selection.Although Charles Darwin never visited the Grand Canyon, he saw rock layers and fossils in other parts of the world.
