And so what we did was we applied this technique and we went backwards in time with the bow and arrow.

And we went forwards in time with the atlatl and dart.

And we found that they crossed over exactly at 1400 years ago.

So that's when the bow and arrow transition from the atlatl and dark occurred in Western North America.

So what you're talking about is the principle of convergent evolution.

And we see that all the time in the biological world, right?

Insects, birds, and bats all can fly.

But they're not related to each other.

They independently evolved the ability to fly.

And so we see that with the bow and arrow, right?

The bow and arrow was invented, we think, in South Africa about 74,000 years ago.

It was invented again in Central Europe about 54,000 years ago.

Sri Lanka 48,000 years ago.

Again in Europe 11,000 years ago.

And what we've shown in this latest paper, it was reinvented once again in North America, just 1400 years ago.

So like, I mean, this is because humans are smart and they have similar issues that they need to solve, problems they need to solve.

And so they'll come up with similar solutions.

And so at various points in time, people invented the bow and arrow to tackle whatever problem they were facing.

Yeah, there's general trends where points will get smaller after that point.

And then like, you know, five or six hundred years after that fourteen hundred year old marker, like the points get real small.
