It took 5,000 years before humans could comfortably digest dairy

If you're lactose intolerant, you probably often give the stink eye to your friends who can enjoy milk, ice cream and pizza without any problem. Now, you can find solace in the fact that humans weren't really meant to digest dairy products.

It took early Europeans 5,000 years after the introduction of farming to evolve the ability to comfortably drink milk, a new study published in the journal Nature Communications on Oct. 21 has found. This is one of the first times ancient DNA has been sequenced.
