Jim Al-Khalili receives Darwin Day Medal
On Friday night, Humanists UK hosted the 2025 Darwin Day Lecture ‘The Evolution of the Human Brain,’ delivered by physicist, author, and broadcaster Professor Jim Al-Khalili. The event explored the history of brain evolution, from the emergence of neurons to the complexity of human cognition, and looked ahead to the implications of artificial intelligence on human identity. The event was chaired by paleobiologist and Humanists UK patron, Professor Anjali Goswami. The story of the human brain Jim traced the brain’s evolution from its earliest origins to the complexity of human cognition. A major turning point was the Cambrian Explosion (530 million years ago), which saw a surge in life’s diversity and the emergence of the first vertebrates – with backbones, spinal cords, and early brains. As life moved onto land, ‘visual processing’ adapted to new environments, and mammals evolved larger, more complex brains. Fossils of Morganucodon, a tiny shrew-like creature, reveal early signs of the neocortex, the region responsible for ‘problem-solving and higher-order thinking’. A key leap came with social intelligence. As primates formed larger …
