You're listening to Bulletproof Radio with Dave Asprey.

Today's cool fact of the day is that human DNA has been found in the bones of a Neanderthal

woman, which puts cross-mating back to at least 110,000 years ago.

That genetic mixing left its mark in the DNA of a Siberian Neanderthal.

It's interesting because we know that many humans today carry little bits of Neanderthal DNA.

I'm very pleased to tell you that I have the Neanderthal gene for less back hair, which is something that I've enjoyed for my entire life.

However, this is the first time that human DNA has been found embedded in Neanderthals genes.

What this finding means is that, well, sorry, we have to re-evaluate all of our scientific theories on the relationship between humans and Neanderthals.

We've had this long string of discoveries that tell us that humans are probably way older than we thought we were.

The history is way more interesting than what we told ourselves based on very limited data.

But now that we can go in and look at DNA, like, wow.

The world is really interesting. We'll put it that way.

Before we get into the show today, you might not know that we make Bulletproof Performance kits.

If you're new to Bulletproof and just looking to try some foundation products, or you're going to upgrade a specific area of your performance,

there are a dozen specialized kits on Bulletproof.com.

If you don't want to have to decide what's the right thing for me, we'll sort of tell you if you want this goal, get this set of things.

That's there just to save your time and to make it easier to make a decision.

I can tell you that when you go Bulletproof, you're going to feel a difference.

The whole point here is I make products that have something you can feel in them.

It's about how you feel when you do it. It's not about, I believe if I do this, I'm probably going to be better at 10 years or now.

You probably will, but you have to feel it right now.

Go to bulletproof.com, check out the performance kits. They're awesome.
