WebSympatric speciation, meaning speciation in the “same homeland,” involves speciation occurring within a parent species while remaining in one location. Biologists think of speciation events as the splitting of one ancestral species into two descendant species. http://www.ib.bioninja.com.au/higher-level/topic-10-genetics-and-evolu/103-gene-pools-and-speciati/speciation.html daf chain

WebAlthough ecological adaptation is thought to be the most important process in most cases, sympatric speciation can also occur through the sole operation of sexual selection (Higashi et al., 1999). Because gene flow is known to have a powerful homogenizing effect on populations, it was generally thought that sympatric speciation would be impossible.
