Silent birds

Hawaii is a great place to study extinction where 140 native bird species are extinct while some have even vanished. Island species that have disappeared maybe explained in that they may a ready meal for invasive species, but geneticists thinks otherwise. Extinction happens as they lose the chance of element of genetic diversity and may even experience some inbreeding problems plus genetic factors may contribute to extinction. But this theory has been questioned. Thus, a measurement was done that measures the genetic diversity while examining the historical genetic signature of the bird species that are extinct. It has been found out that the levels of the genetic diversity is within that of the common species while others were found to have less diversity. Furthermore, DNA and genetic data provide the genetic understanding of extinction in Hawaii.
