TED-Ed: Is human evolution speeding up or slowing down? | Laurence Hurst

The video explores human genetic adaptations, focusing on Tibetans' ability to thrive at high altitudes due to genetic changes. It discusses other adaptations, like those in Siberians and Bajau people, and the ability to digest milk. Modern medicine's role in altering natural selection and increasing genetic drift is examined. The potential for rapid genetic changes through epigenetics and the impact of technology on future evolution are also considered.

Why is it important to consider other aspects of evolution besides natural selection?

What is genetic drift and how does it relate to modern medicine?

What are epigenetic modifications and how might they affect evolution?
