adaptative radiation - diversification of a group of organisms into forms filling different ecological niches allopatric speciation - aka geographical isolation: biological pops of the same species become isolated from each other to an extent that prevents or interferes with gene flow allopolyploidy - individual or strain whose chromosomes are composed of more than two genomes each of which has been derived more or less complete but possibly modified from one of two or more species -matin...
