WebSpeciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation. In sympatric speciation, groups from the same ancestral population evolve … WebThey will use taxonomy. It's a centuries-old science, used to identify species. First, they examine specimens of the organism, try to see whether it matches known species, and then use molecular biological assay techniques to further identify, if needed, its place in evolutionary history. This is normal science.
