Complete genome sequencing of two woolly mammoth (Mammuthus primigenius) specimens that lived approximately 4,300 and 44,800 years ago has been completed by researchers. The younger specimen was a member  of one of last surviving mammoth populations.

The researchers concluded that the woolly mammoth experienced a temporary population decline before recovering. This resulted in a reduction of genetic diversity within the species before it became extinct.

The two specimens were found in Russia on Wrangel Island (4,300 year-old specimen) and northeastern Siberia (44,800 year-old specimen).
