When We First Talked

The video explores the evolution of human speech, highlighting the unique vocal abilities of humans compared to other animals. It delves into the fossil record, focusing on the hyoid bone and vocal tract proportions, to understand when and how speech capabilities developed. The video also examines the hearing abilities of early hominins and their potential for language, suggesting that while they may not have had language as we define it, they had the anatomical capacity for human-like speech sounds.
