The Genes We Lost Along the Way

The video explores the concept of molecular fossils in our genome, focusing on extinct genes like GULOP and UoX. It explains how mutations lead to gene death and how these changes can impact evolution. The loss of GULOP affected vitamin C synthesis in primates, while the UoX gene's inactivation influenced uric acid levels and fat storage. The video also discusses the evolution of taste receptors in response to dietary changes, highlighting the role of gene loss in shaping our evolutionary history.
