Evolution of Music and Sleep Disorders

The video discusses the evolution of popular music over the last 50 years, using evolutionary biology techniques to analyze changes in music genres like rock, rap, and jazz. It highlights significant evolutionary spikes in music in 1964, 1983, and 1991, with rap emerging as a dominant genre. The video also covers a study on genetic links between sleepwalking and sleep terrors, showing a hereditary pattern in these sleep disorders. The video concludes with a call for support on Patreon.
