Are Humans The Only Species To Drink Milk Of Other Species?

The video explores the history and biology of milk consumption across species. Humans are unique in drinking milk from other species into adulthood, a practice that began with the domestication of animals. This led to a genetic mutation in some humans allowing them to digest lactose. While most animals lose the ability to digest milk after infancy, some rare instances of interspecies milk consumption occur in the wild.

What genetic mutation allowed some humans to digest milk into adulthood?
