hyoid bone

But

again, but that's why I'm so glad that they have that, what's that called with the broken bone again? Hyroid.

Yeah, I'm so glad that that is the unusual part of it, at

least.

Yeah.

Definitely.

The problem is we not only find genetic level discontinuities we also find fossil discontinuities one major discontinuity is the hyoid which.

is essential for our ability to speak as humans sophisticated speech it turns out that the human hyoid is more similar to the Neanderthal hyoid and other human hyoids than to the Australopithecine hyoid bones or the extant apes.

Extant apes like chimpanzees and Australopithecines were designed in a similar way where they're not capable of human speech.

And so the question is, where is the transitional hyoid form between the ape-like bola and human bar-shaped design? Where is the fossil evidence showing the gradual emergence of human speech anatomy? There's other discontinuities as well, like the skulls of the Australopithecines compared to modern humans, the ischium aspect of the pelvis as well.

As for the first question, what's the explanation? Well, yeah, so we know the mechanisms of we know the mechanisms of evolution.

I went over some of them in my opener, right? Variation, inheritance, mutation, all of these things.

You can have a series where there is some incremental series of hyoid bones in the fossil record.

There's nothing There's nothing in terms of the morphology difference between these things where you can't have an incremental succession of them.
