Seeing some comments about how they didn’t actually trace the steps. Okay, yeah, they didn’t. But what they did do is so damn cool — science at its best. I’m kind of in awe that we roughly know what happened in a mammoth’s life from 17,000 years ago — including [spoiler alert] the fact that it eventually starved to death at 28.
You can find the map showing the path of the mammoth from the paper here:<p><a href="https://science.sciencemag.org/content/sci/373/6556/806/F2.large.jpg" rel="nofollow">https://science.sciencemag.org/content/sci/373/6556/806/F2.l...</a>
They didn't retrace <i>steps</i>, they analyzed isotopes concentrations in different parts of tusks, which were constantly growing through the lifetime of the mammoth.
They do this to a lesser degree with human teeth and bones, but not with a precision of long, continuously growing tusk.In addition human tarter reveals diet.
