Yeah, and if you look them up, they look very planet of the apes.

Anyway, a study out this week in the journal Cell may have solved the size mystery.

An international team of researchers analyzed the teeth of 20 Homo naledi individuals spanning thousands of years to determine the sex.

Oh, interesting.

So how big of a deal would that be if it's true?

It could be a big deal because Homo naledi isn't in our direct lineage and burial practices are largely ascribed to humans.

Although other animals do it like elephants and naked mole rats.

Interesting.

So how are others in the field reacting to these findings?

Yeah, so how humans evolved to communicate is not totally clear.

I mean, we don't have recordings of our hominid ancestors, you know, talking.

But we can study some distant relatives, the great apes.

There are orangutans, gorillas, chimpanzees, empanobos.

And so how they communicate and vocalize could give us clues about our own evolution.

Yeah, they basically made us laugh, right?

And we're actually more closely related to bonobos and chimpanzees out of all the great apes.

And our laughter is the most similar to theirs, like you said.

So this study shows us that as a species becomes more social, maybe laughter gradually evolves as well.

And that laughter conveys really important information.

So, Anna, with all this laughing in mind, we have a joke for you.
