The video discusses the evolution of lactose tolerance and starch digestion in humans. It highlights the lactase gene's role in allowing some adults to digest lactose, a trait that evolved due to mutations in certain populations. The amylase gene, responsible for starch digestion, varies in copy number among individuals, affecting their ability to process starch-rich foods. The video also compares these human adaptations to chimpanzees, illustrating the evolutionary divergence in digestion-related genes.
