We find evidence for very early mutations impacting the facial phenotype, and much more recent molecular events linked to specific brain regions such as the cerebellum or the precuneus. 2/
I enjoyed working on this with my students @AGMAndirko & @juanandres_mp in otherwise difficult circumstances (lockdowns). They are terrific researchers. I am thankful for the opportunity to work again with friends @MKuhlwilm@polvere7@gtesta72, the best part of the job, IMO. 3/
Beautiful work from J. Wysocka's lab out in @CellStemCell: Loss of Extreme Long-Range Enhancers in Human Neural Crest Drives a Craniofacial Disorder (h/t @polvere7) [Thread 1/] cell.com/cell-stem-cell…
The study shows how mandible development is sensitive to perturbation of SOX9 gene dosage 2/
"even such a slight reduction in Sox9 gene dosage results in measurable changes in lower jaw shape and reduction in postnatal growth" 3/
Very cool comparative cognition study (h/t @Limor_Raviv) making “the case for the universality of the sequence organization observable in informal human conversational interaction” 1/
My favorite part comes at the end, where the authors note “one of the most basic units of human social interaction, ..., has apparent homologs in the social interaction of nonhuman primates” but 2/
they find “the more elaborate structures that occur in human interaction” lacking in our closest living relatives. Why? “non-human primates appear to be limited in their ability to learn and represent the hierarchical structure of sequences” 3/
Enjoyed reading @rcbregman's new book "Humankind"; a good companion to R. Wrangham's "Goodness Paradox" and @bharedogguy & @bonobohandshake's forthcoming "Survival of the Friendliest". 1/
The paper’s core message is that we must avoid too narrow a definition of the vocal learning phenotype if we are to shed light on its evolutionary trajectory and (neuro)biological underpinnings
We recognize that there has been a tremendous amount of progress in this area already — indeed, it’s arguably one of the most successful research areas touching on key aspects of language.
As the semester comes to an end here, I thought it might be worth highlighting a few terrific pieces that I have used early on in class before we picked up speed. They are superb entry points for complex issues: 1/
