nature in an experiment i have no yet why is like so far like it sounds so simple they had no idea

but now the data's i find this not only refreshing but but at some level astounding nature

welcome back to the Nature.

Welcome back to the nature podcast.

This week, the ancient hominins in your DNA.

And the origin of an unusual object at the edge of the solar system.

I'm Chamni Bandell.

And I'm Nick Howell. First up on the show, how the genomes of modern humans can tell us about our past.

You're probably a little bit Neanderthal.

Once upon a time you may have considered that an insult, but these days a lot of people

are familiar with the idea that all humans outside of Africa can trace a little bit of

their DNA around 2% to these now extinct hominins.

And scientists are able to take advantage of that fact

to learn more about Neanderthals.

And one way you can do that is you can sequence a lot of modern humans.

And because our ancestors, when they left Africa,

met and exchanged with these Neanderthals,

looking at a lot of samples, you can actually reconstruct

what the Neanderthal population look like.

This is Lowrit Scov, a bioinformatician with an interest in ancient hominens.

This week in nature, to get a better understanding of our Neanderthal cousins,

he and his colleagues have been looking at genomic data from over
