Woolly mammoths once ruled the northern reaches of our planet, roaming from Portugal to

Siberia and beyond, to Alaska, Canada, and the American Midwest. And the massive beasts left

lots of fossil evidence of their occupation. But now scientists have noticed a strange trend

among those mammoth remains. The researchers genetically analyzed the fossilized bones, teeth,

and tusks of 98 individual Siberian mammoths. And they found that 70% of the mammoths were males.

So essentially we think this is driven by two different things.

Louvedalian, a paleogeneticist and professor at the Swedish Museum of Natural History in Stockholm.

In general, in wild animals, males tend to be more risk-taking.

The second thing, if modern elephant culture is an indication,

is that male mammoths may have been solitary loners, more likely to

crash through thin ice and sink holes or get caught in a mudslide than females. Those types of

death are also more likely to become preserved, so those are the remains that we find today. The

studies in the journal Current Biology. Deland says this is an important reminder that the fossil record is far from complete.

Fossils we find might not always be representative of the species back when it lived.

But with a little detective work, even seemingly random remains, have much to reveal.
