🧬🐣 Researchers found that #chickens and #humans share genetic blueprints for facial growth.

While the instructions are similar, the timing and way #cells respond to signals create unique shapes, explaining how #evolution produces diverse features.

This week's #NewBooks at the library: Another three books from our January clearance sale, some of which have been review candidates for some time now.

- Planet Palm: How Palm Oil Ended Up in Everything – and Endangered the World, a shocking and eye-opening reportage written by Jocelyn C. Zuckerman and published by Hurst Publishers.

- Making Faces: The Evolutionary Origins of the Human Face, written by Adam S. Wilkins, published by Belknap Press. Not one I was planning to review, but I find it very hard to pass up a bargain on an interesting book on human evolution and physical anthropology.

- Unfit for Purpose: When Human Evolution Collides with the Modern World, written by Adam Hart, published by Bloomsbury Sigma. One of several books that explores the mismatch between our evolutionary legacy and the modern world we have created for ourselves. I expect them to be amusing reads all!

✋🧠 Humans have used finger joints and palms as portable #memory devices for over a millennium to track calendar dates and musical scales.

These manual systems provided both visual and physical ways to store information independently of written manuscripts. Modern examples include tracking the length of months on knuckles or applying #physics rules in the classroom.

Trabecular cartilage (Evolution 🧬)

Trabecular cartilages are paired, rod-shaped cartilages, which develop in the head of the vertebrate embryo. They are the primordia of the anterior part of the cranial base, and are derived from the cranial neural crest cells.

Another cool #Anatomy paper on the connectivity between #BasalGanglia and the #Cerebellum

Here some quotes:

"Neural processing in the basal ganglia is critical for normal movement.
...
Many believe that the basal ganglia influence movement via thalamic projections to motor areas of the cerebral cortex and through projections to the cerebellum, which also projects to the motor cortex via the thalamus.
...
However, lesions that interrupt these thalamic pathways to the cortex have little effect on many movements, including limb movements.
...
In this report, we describe several brainstem pathways that connect basal ganglia output to the cerebellum via nucleus reticularis tegmenti pontis (NRTP).
...
The basal ganglia could ... alter movements via descending projections of the cerebellum.
...
Pathways through NRTP ... may underlie deficits associated with basal ganglia disease."
