Although not the only agent of evolutionary change, natural selection is certainly the most important mechanism of adaptive evolutionary change in populations of organisms. Through the process of natural selection, individual organisms become better...
Breeding systems in plants refer to the variety of ways plants answer the general question of "Who mates with whom" by answering specific questions such as whether flowers mature at the same time, whether a plant has more than one kind of...
Evolution and the theory of natural selection are the principle unifying concepts in biology. This is as true now in the age of molecular biology as it was a century ago. The unification stems from the fact that details of embryology, morphology,...
Natural selection is the differential survival and reproduction of individuals with particular phenotypes, the physical manifestation of genotypes. Natural selection works only on the phenotypes of individuals. Natural selection produces adaptation...
Natural selection is the process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common. Natural selection acts on...

Analogies and parallels exist between Charles Darwin's evolutionary model of natural selection and Adam Smith's capitalist economy. In studying both systems -- one the law of the wild, the other a system imposed by humanity -- we can see how similar they are in their mechanisms, despite their applications to completely different settings. Not surprisingly, therefore, Smith's capitalist system brings human society closer than ever to the brutal characteristics of the natural world, the same characteristic
