An fashion model of this would be that there are around sextuplet different species of mos quitoes that are similar but cannot all interbreed with one another because they breed in different waters. and then it creates more species of mosquitoes. Another alter isolating mechanism to speciation in organisms would be behavioral isolation.

This occurs when suit of clothes rituals enable mate recognition, which is the way one animal behaves to tint another animal to deprivation to mate. A great example of this is Blue footed boobies. The males attract the females with their bright blue feet; hence they only mate with one another because of the similar mating behavior. Polyploidy is also a contributor to the speciation of organisms. Polyploidy occurs when a species may sprin g up from an accident during cell theatrica! l role that results in unneeded chromosomes, all derived from the same species.
