Long before factories, mines, and cars filled the air with pollution, our distant ancestors were already living with a silent toxin: lead. A groundbreaking study reveals that hominids — from early ...

Humans' unique language capacity was present at least 135,000 years ago, according to a survey of genomic evidence. As such, language might have entered social use 100,000 years ago. It is a deep ...

At some point, early humans began to communicate in ways that went beyond simple sounds. Language developed gradually, shaped ...

It is a deep question, from deep in our history: when did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ...

Researchers found that ancient hominids—including early humans—were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven ...
