In a study published in the journal Current Biology on Thursday, an international team of researchers announced they had sequenced the woolly mammoth's complete genome, using stem cells from an African elephant as a test. That is amazing in and of itself, but the results also reveal interesting new insights into the wooly mammoth's extinction.
As part of their research, the scientists compared DNA from two different woolly mammoths. One lived in Siberia about 44,800 years ago, and the other lived on Wrangel Island, where the last surviving mammoths died, about 4,300 years ago.
