Divergent evolution is the process of two or more related species becoming more and more dissimilar, while convergent evolution is unrelated species becoming more similar in appearance as they adapt to the same environme... More »

Divergent evolution is the mechanism that causes different species to arise from common ancestors, the evolution toward greater difference in related organisms. In the classification system it is a part of, it is one of ... More »

Divergent evolution happens with the formulation of a new species from a larger population, explains JRank. Evolutionary adaptations necessary for survival cause a subset within a population to adapt differently to the p... More »

Adaptive evolution refers to changes within species as a result of stimuli in the environment, and one example is Hypericum perforatum, also known as St. John's wort. This plant now has latitudinal clines in a number of ... More »

A generalist species is one that can live in a wide variety of habitats and have a varied diet, while specialist species are adapted to a particular environment or a specific diet. Koalas and tiger salamanders are exampl... More »

Lamarck's theory of evolution differs from Darwin's in its premise that adaptations appear when needed in response to the environment and the acquired traits are then passed on to offspring. Genetic research, however, ha... More »

Charles Darwin is best known for establishing a theory of evolution that explains biological changes among the species of the Earth. His belief that most species evolved through the process of natural selection also made... More »
