Using game theory, they were able to test a variety of evolutionary strategies to see which one what is selection in population genetics with the highest average payoff, explaining why animals have only evolved limited war strategy, in which risk of serious injury is low.

It seemed as though the trend that produced the antlers, popultaion originally for some useful purpose, had acquired a momentum of its own that had carried it far beyond the point of utility. With different formulations, such ideas have been applied to several fields, including biology, anthropology and education theory. Selection and measures of fitness, pp. Berg translationbut perhaps its best known exponent was the American paleontologist Henry Fairfield Osborn.

Systematics and what is selection in population genetics origin of species. Maynard SmithP. They are surrounded by two membranes, the inner of which is folded into invaginations called cristae, where aerobic respiration takes place. Internal fertilization has evolved independently in sharks, some amphibians and amniotes. Contrast with catastrophismpunctuated equilibrium.

Plant species hybridize more readily than animal species, and the resulting hybrids are more often fertile hybrids and may reproduce, though there still exist sterile hybrids and selective hybrid elimination where the offspring are less able to survive and are thus eliminated before they can reproduce. Transitional formor transitional fossil A fossil or group of organisms that are intermediate and a link between a more primitive or ancestral group and a more advanced or specialised one, possessing characteristics or traits of both see Mosaic evolution. Gradual evolution or phyletic gradualism occurs where change is small and constant; punctuated evolution where change is very rapid, while most of the time there is virtually no change.
