A third kind of speciation, called sympatric (Gr. sym, together)
speciation, occurs within a single population. Even though organisms
are sympatric, they still may be reproductively isolated from
one another. Many plant species are capable of producing viable
forms with multiple sets of chromosomes. Such events could lead
to sympatric speciation among groups in the same habitat. While
sympatric speciation in animals is uncommon, it has been documented
in two species of bats and several species of insects and fish.
