Researchers found that ancient genetic "switches," known as HAQERs, have an outsized influence on language ability, despite making up less than 0.1% of the genome, and these regions were already present in Neanderthals.

Why
HAQERs, acting like volume controls for genes involved in brain development, helped build the brain's biological "hardware" necessary for language, suggesting ancient origins for sophisticated communication.
The Frontline Impact

How this affects you

This discovery sheds light on the genetic underpinnings of human language, indicating that the biological capacity for language might be more ancient than previously thought, potentially existing in Neanderthals. Understanding these genetic "switches" could offer insights into language development and disorders.
