speciation

The formation of different (inorganic) species, for example in a gas

The process by which new distinct species evolve

In both groups, however, we find copious and intricate speciation so that, often, species limits are narrow and ill defined.

1 The process whereby a new species comes about The most common cause of speciation is that of geographical isolation

The formation of different (inorganic) species for example in a gas

The evolution of one or more species from an existing species

the evolutionary process that gives rise to a new species

determination of particular chemical forms of an element, rather than just the total element Metals may be speciated by oxidation state (Cr(VI) vs Cr(III), for example,) or by successively stronger extractions from a solid sample

the process by which one or more populations of a species become genetically different enough to form a new species The process often requires populations to be isolated for a long period of time

An analysis of the form in which a contaminant (such as a metal) exists in soil, which will help determine the source of the contaminant

the evolution of a biological species

the process of species formation

separation of one population into two or more reproductively isolated, independent evolutionary units

Commercial silicates are complex mixtures of silicate anions of different molecular size Speciation describes the distribution of these anions The distribution depends on silica: alkali ratio and/or solids concentration

The process by which new species originate through mutations, natural selection, and evolution

The creation of a species through the splitting of one species into two or more, through descent

Formation of new and distinct species, whereby a single evolutionary line splits into two or more genetically independent ones. One of the fundamental processes of evolution, speciation may occur in many ways. Investigators formerly found evidence for speciation in the fossil record by tracing sequential changes in the structure and form of organisms. Genetic studies now show that such changes do not always accompany speciation, since many apparently identical groups are in fact reproductively isolated (i.e., they can no longer produce viable offspring through interbreeding). Polyploidy (see ploidy) is a means by which the beginnings of new species are created in just two or three generations

The evolutionary splitting of lineages

The evolution of new species

This is the evolution of multiple species from a single founding (ancestral) species Closely related forms are usually defined as species if there is some form of reproductive isolation see [1: peripatric speciation ]; [3: speciation]; [3: sympatric speciation]; [3: Observed Instances of Speciation]; [3: the concept of species ]; [ the species concept]; [ What is a Species, and What is Not? by ERNST MAYR]; [3: Speciation ]
