Understanding the crocodilian genome can help scientists better understand birds. The DNA in alligators, crocodiles and gharials is about 93 percent identical across the genome. By comparison, a human shares about 93 percent of his or her DNA with a macaque. Leer más.
Disjunct geographic distribution of a species or a group of species is the product of long-term interaction between organisms and the environment. Filling the distributional gap by discovery of a new population or a species has significant biogeographic implications, because it suggests a much wider past distribution and provides evidence for the route of range expansion/contraction.

Poring over records to find out, the researchers saw that a comparable frog had been collected in the area 10 years earlier, but it was written off then as a species from an Indonesian island about 450 miles to the west. The distance and geography between the two habitats made them suspect their frog might have been formerly misidentified. Leer más.
