One criterion for identifying products of this process differentiates between pre-zygotic and post-zygotic isolation.
One criterion for identifying products of this process differentiates between pre-zygotic and post-zygotic isolation. In plants this process commonly occurs by polyploidy, which is more rapid than other types of this process. The sympatric form of this process can occur via disruptive selection when populations are not in geographic isolation, while the closing of the Isthmus of Panama led to the allopatric type of this process. This process can also occur via hybridization when two populations interbreed. For 10 points, name this process by which new classes of organisms are formed.
