Interest in Elemental Speciation Analysis â¢ Speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. â The chemical species are specific forms of an element defined as to isotopic composition, electronic or oxidation state, and/or complex or molecular structure. â¢ Different forms of an element can have totally different properties. â Essential for predicting and modeling fate, risk, and effects, Critical for toxicology,
This could produce a number of individuals that have a mutation that would make them unable to deal with life in that environment. Or the same change would allow them to do exceedingly well. This mutation would, over a very long time, produce a different species. Speciation that results when a population is separated by a physical barrier is allopatric speciation. Sympatric speciation is speciation that occurs without physical separation of members of the population. Some examples of sympatric changes occurred long ago when people live in small villages.
