Karaoke Lemurs and the Evolution of Music

The video explores the evolution of tusks in mammals, focusing on research into ancient dycynodons. It defines tusks as continuously growing protrusions made of dentin, not enamel. The study reveals that tusks evolved multiple times in different species. Additionally, the video discusses a study on lemurs, showing that their songs have human-like rhythmic patterns, suggesting universals in music across species.
