Speciation

the process by which new species arise. The process by which discontinuities between populations occur due to the development of mechanisms creating the reproductive isolation of one population from the other. Allopatric speciation: species formation that occurs during geographic isolation of populations. Generally believed to be the most common w

Speciation

Speciation is the process in which a single species differentiates into two distinct species. One method by which this occurs is geographic isolation, in which two subpopulations of a single species are separated and no longer interbreed. Since the pressures of natural selection differ for the two groups, the two populations become more and more di

speciation

A group of organisms that are able to interbreed all belong to the same species. It follows then that organisms that are unable to interbreed belong to separate species.

speciation

Emergence of a new species during evolutionary history. One cause of speciation is the geographical separation of populations of the parent species, followed by reproductive isolation and selection for different environments so that they no longer produce viable offspring when they interbreed. Other causes are assortative mating and the establishme

Speciation

[genetic algorithm] Speciation is a process that occurs naturally in evolution and is modeled explicitly in some genetic algorithms. Speciation in nature occurs when two similar reproducing beings evolve to become too dissimilar to share genetic information effectively or correctly. In the case of living organisms, they are incapable of mat

Speciation

Speciation is the evolutionary process by which new biological species arise. The biologist Orator F. Cook was the first to coin the term `speciation` for the splitting of lineages or `cladogenesis,` as opposed to `anagenesis` or `phyletic evolution` occurring within lineages. Whether genetic drift is a minor or major contributor to specia...
