Dragons and Brain Evolution

Researchers created a molecular atlas of the bearded dragon's brain and compared it to the mouse brain. Findings reveal, contrary to popular belief, mammalian brains consist of an ancient reptilian brain supplemented with new mammalian features. Both reptilian and mammalian brains evolved their own clade-specific neuron types and circuits from a common ancestral set.

When Humans Gesture, They Activate an Ancient Connection Between Movement and Breathing

A new study sheds light on why humans often use hand movements while talking. Researchers report rhythmic hand gestures affect rib cage movements, leading to a change in lung volume and ultimately aspects of the voice. Infants connect early vocal babbling with hand gestures, demonstrating an early connection between movement and vocal production.
