The Bizarre Evolution of Hemipenes (yes...hemipenes.)

The video explores the evolutionary history of snakes, focusing on their loss of limbs and the development of hemipenes. It discusses the genetic factors involved in limb development, the role of transcription factors, and the connection between limb enhancers and genital development. The video also examines the diversity and function of hemipenes in snakes, highlighting their evolutionary advantages. Finally, it emphasizes the need for further research to understand the genetic mechanisms behind these developments.
