WebEvolution is a biological process. It is how living things change over time and how new species develop. The theory of evolution explains how evolution works, and how living and extinct things have come to be the way they are. The theory of evolution is a very important idea in biology.

Stabilizing selection is a descriptive term for what happens to an individual trait when the extremes of the trait are selected against. This increases the frequency of the trait in the population, and the alleles and genes …

WebIn primate: General structure. Specialization is not always a liability; in times of environmental stability, the specialized animal enjoys many advantages, but, in a rapidly changing world, it is the less-specialized animals that are more likely to survive and flourish. The plasticity of primate behaviour is largely a function….
WebEvolutionary biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to other genotypes. So if brown beetles consistently leave more offspring than green beetles because of their color, you'd say that the brown beetles had a higher fitness. In evolution, fitness is about success at
