The origin of new species in evolution.

Distribution of an element amongst defined chemical species in a system. [3]

1906; see species + -ation. The verb speciate is a back-formation attested by 1961.

process by which one or more populations of a species become genetically different enough to form a new species. Read more in the NG Education Encyclopedia

the evolution of a new species. This usually happens through either geographical separation over long periods of time, or through reinforcement

Speciation is the evolutionary process by which a new species comes into being

The process by which two or more species are formed from a single ancestral stock. species diversity

the formation of a new species where a population splits in 2 that are isolated from each other.

  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.

The process by which new species are evolved. Some of the confusion with this term can be seen in the natural history account of the

Formation of species via the process of selection - natural or artificial.

the process by which new species are formed.

the formation of one or more species from a common ancestor.

Changes in related organisms to the point where they are different enough to be considered separate species. This occurs when populations of one species are separated and adapt to their new environmen [..]

Speciation is the process of forming two new species from a common ancestor species. Speciation is the central process of macroevolution, the evolution of novel forms.

The process by which new species are formed.

the evolution of new species. May be through cladogenesis, where one parent species splits into two new ones, or anagenesis, where one species gradually changes into another.

(n) the evolution of a biological species

the splitting of one phyletic lineage into two or more.

formation of new species.

A natural process usually resulting in an increase in the number of species in a particular group. Speciation is not a single process but an array of processes and it may be reticulate or non-reticula [..]

The splitting of an ancestral species into daughter species that coexist in Time (King, Dictionary of Genetics, 6th ed). Causal factors may include geographic isolation, HABITAT geometry, migration, R [..]

Speciation is the process in which a new species is formed from an initial one. The following events must happen in the origin of a new species: 1. There is a single species, made up of a set of inter [..]

The process whereby species multiply; the acquisition of reproductive isolation between populations, splitting one species into two.

    The evolutionary splitting of lineages.

The process by which new distinct species evolve.

The development of new species as a result of evolutionary processes.

Speciation is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample.

The evolution or formation of a species.

Evolution of reproductive isolation within an ancestral species, resulting in two or more descendant species.

the evolution of a species

The determination of the number of species into which a single species may evolve over time
