Where the white sharks are ...


"Studies of maternally inherited mitochondrial DNA sequences show that the populations are distinct, and suggest that the northeastern Pacific population may have been founded by a relatively small number of sharks in the late Pleistocene - within the last 200,000 years or so.

According to Molecular geneticist Carol Reeb, a research associate at Stanford, “Even though we know they travel great distances, their paths are surprisingly constrained to specific routes. This explains how a highly migratory marine species becomes a genetically isolated population.”
