noun, plural: speciations
The process in which new genetically distinct species evolve usually as a result of genetic isolation from the main population
Due to genetic isolation, the differences in gene pool among species become so great that they cannot reproduce through interbreeding. As a result, new species are formed with a genome that is genetically distinct from the main population.
The ways in which new species are formed are as follows:
Word origin: from Latin speciēs, a seeing, kind, form + L -ātiōn- (s. of -ātiō), action or process.
Related forms: speciate (verb), speciational (adjective).
