The thick coats of shaggy hair that kept woolly mammoths warm on the icy tundra have yielded enough intact DNA to sequence their genomes, a new study reports.

In addition to helping scientists figure out why mammoths went extinct, the feat could pave the way for better and faster genetic studies of other ancient animals.
