This is due to a genetic mutation that first occured about 8k years ago, and significantly improved survivability in populations that had it. The claim in OP is therefore false https://www.npr.org/sections/thesalt/2012/12/27/168144785/an-evolutionary-whodunit-how-did-humans-develop-lactose-tolerance
