Term Definition
genetic drift a change in allele frequencies of a population due to a chance process
speciation the formation of a new species from a single ansestoral species
allopatric speciation occurs when a popuation is seperated by a geographical barrier
sympatry when a subpopulation becomes reproductively isolated in the midst of a parent population
polyploidy abrupt formation of a new species form non-disjunction
divergent evolution geographical and reproductive isolation of a population from the main gene pool
adaptive radiation the emergence of many species each adapted to a specific ecological niche
convergent evolution independent evolution of adaptive features in different species
parallel evolution evolution of similar features not present in the ancestoral form in two or more related species

rgresson : Changed parallel evoloution → evoloution of similar features not present in the ancestoral form in two or more related species to parallel evolution → evoloution of similar features not present in the ancestoral form in two or more related species
rgresson : Changed sympatric → when a subpopulation becomes reproductively isolated in the midst of a parent population to sympatry → when a subpopulation becomes reproductively isolated in the midst of a parent population
rgresson : Changed convergent evoloution → independent evoloution of adaptive features in different species to convergent evolution → independent evolution of adaptive features in different species
rgresson : Changed parallel evolution → evoloution of similar features not present in the ancestoral form in two or more related species to parallel evolution → evolution of similar features not present in the ancestoral form in two or more related species
rgresson : Changed polypliody → abrupt formation of a new species form non-disjunction to polyploidy → abrupt formation of a new species form non-disjunction
