Sympatric Speciation

Nathan Merrill 3/3/2003 CE AP Biology – Period 3 Sympatric Speciation Sympatric speciation is when two geographically overlapping populations become reproductively isolated and speciate. For many years sympatric speciation was thought a minor player at most in speciation, but now it seems it may play a much larger role. For sympatric speciation to occur, a couple factors must come into play. First, mating must be non-random: if members of the species mate completely at random, then unique traits will not gain much hold. The second factor is some sort of selective factor which may cause the non-random mating. This
