- At1:55and thereafter when he introduces the concept of the difference in the bottom of the human skull, is he saying "flex bottom of the skull"? Or something else? Because when I google this to learn more I find nothing, so I think I must be mis-hearing it.
The bigger question I'm wondering: Can anyone point me to further resources about this anatomical difference in our skull? I found https://www.speechbuddy.com/blog/news/speech-evolution-origin-of-language-humans-are-awesome/ which says our larynx is much lower than other species and our oropharanx (mouth and throat) is L-shaped compared to other species, but I don't see anything about the bottom of the skull. Is he perhaps talking about the soft palate?(1 vote)- At1:55, he is saying the flexed bottom of the skull. I found some reading that I've attached which might explain it further, but it is too academic for me to summarize well.
