Definitions for "Speciation"
the development of a new species by evolutionary processes.
A process whereby over time one species evolves into a different species (anagenesis) or whereby one species diverges to become two or more species (cladogenesis).
Formation of new species from old ones, by any process (reproduction isolation; genetic impoverishment; pre-formist selection, etc.)
The evolution of one or more species from an existing species.
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 development of a species through evolution. A species forms when its members become reproductively isolated from all other organisms. Speciation can occur through geographic separation that eliminates gene flow or through adaptive radiation.
The form or "species" taken by a metal. Metals such as copper can appear in numerous forms in the Chesapeake Bay, some far more toxic than others.
Determination of the exact chemical form or compound in which an element occurs in a sample, for instance - determination of whether arsenic occurs in the form of trivalent or pentavalent ions or as part of an organic molecule, and the quantitative distribution of the different chemical forms that may coexist.
(4) the chemical form in which an element is present or the process whereby various states or forms of an element become differentiated into ions.
