Got Lactase?

Human babies drink milk; it's the food especially provided for them by their mothers. Various cultures have also added the milk of other mammals to their diet and adults think nothing of downing a glass of cows' milk. But worldwide, only a third of adults can actually digest lactose, the sugar in milk. In this short film we follow human geneticist Spencer Wells, Director of the Genographic Project of the National Geographic Society, as he tracks down the genetic changes associated with the ability to digest lactose as adults, tracing the origin of the trait to less than 10,000 years ago, a time when some human populations started domesticating animals, including goats, sheep, and cows. Combining genetics, chemistry, and anthropology, this story provides a compelling example of the co-evolution of human genes and human culture.

Glad i have lactase persistence, even though i rarely consume milk, it's nice to have options.

[@pandakabob8013]

That cat at 2:30 was like "Hey man! Why even call me over if youre not gonna give me my drink!"

[@jennaferhuffstetler6622]

[@Spyrit2011]

I hit the evolutionary jackpot! I can drink milk with 0 problems, as an adult.

[@thesuperproify]

I'm chinese and I'm mildly intolerant. doesn't make any real differences though, milk is not part of our daily diet

[@Msizyke41]

+thesuperproify I guess that makes sense, chinese are generally intolerant

[@chinmayagrawal9398]

Anyone know the main concepts about this video here?cause I don't feel like watching it.

[@nildamariadinizrojas8610]

Do you mean about co-evolution? Niche construction or natural selection?

[@vxkvesk5264]

anyone else looking for faxx here cuz the video too boring?

[@trackingtko]

yes what about what the Eat Right for Your Blood Type diet says? that type B thrives on milk and also what about raw milk verses pasteurized thank u wish we knew much more about this drink :)

[@Spyrit2011]

Pasteurization is just heating milk up to the temperature that kill bacteria.

[@joshalaniz9762]

Anybody watchin from sato?

[@kitsurubami]

it's cute how they didn't show america or south america at all :(

[@Scroatydog]

kitsurubami It only occurred in Europe and Africa and humans in the Americas hadn't domesticated animals...look in the latest NGM - they do include the Americas.

[@kitsurubami]

Scott Sutherland i was joking.

[@Scroatydog]

kitsurubami Fair enough

[@caatabatic]

I would know soon after I finished that liter of milk that I was not tolerant. that kind of amount would have triggered some horrible effects.

[@pedrobatista7975]

I drink a liter every day before sleep (cuz I'm fcking huge) and nothing happens!
