Brain Changes Enabling Speech and Abstract Words

How complex language evolved during the cognitive revolution, changing humanity and the world.

Discover how language transformed from simple grunts and hand signals to complex communication, enabling us to cooperate, create cultures, invent stuff and build civilizations. We explore the evolution of human imagination, the role of gossip, the development of societal morals, and the paradoxical nature of human violence and compassion.

Additionally, we discuss the future of communication technology and the potential mind-blowing implications of brain-computer interfaces. Packed with insights from anthropology, psychology, and neuroscience, this episode provides a comprehensive understanding of our past and a glimpse into our possible future.
