However, there are likely millions of genetic differences between the genome of an Asian elephant and that of a mammoth, according to Shapiro. Apparently, P1 is conical, smaller than the remaining premolars and lacks accessory denticles. These whales were about 16 feet long and weighed around 1,000 pounds or half a ton.

It's unlikely that we'll see a dodo walking the Earth again anytime soon, according to evolutionary molecular biologist Beth Shapiro, a professor in the Department of Ecology and Evolutionary Biology at the University of California, Santa Cruz.
