Working with two mammoth specimens excavated from different parts of Russia and from different eras -- one nearly 45,000 years old, the other just 4,300 years old -- an international team of scientists has sequenced a nearly complete genome for the extinct pachyderm. The achievement provides the most complete snapshot yet of what a woolly mammoth was, which also means we're as close as we've been in a few thousand years to seeing, in person again, what a mammoth...
