A groundbreaking study reveals that lead exposure nearly two million years ago may have influenced human evolution and language development. Researchers found that early Homo sapiens had a genetic advantage over Neanderthals, enhancing their communication skills in toxic environments.
New research reveals a single genetic mutation in the NOVA1 gene may explain why humans developed complex speech while Neanderthals could not. This tiny change in a brain protein has vast implications for understanding human communication.
