A while back I went to the doctors and they diagnosed me as being lactose intolerant after telling them I have been experiencing stomach pain akin to eating one hundred bowls of cambuulo or bean burritos. I went a few months avoiding dairy products meaning no cheese pizza, milk, yogurts etc. before I discovered lactaid pills which contains enzyme supplement that helps digest lactose.
Human as babies all have lactose tolerance but they gradually lose it as they get older like what happened to me. Humans having lactose tolerance for their whole lives is something that came about a few thousands years ago when our bodies evolved to produce lactase the enyzme that breaks down lactose beyond our baby years. Today other than the cadaans ,the rest of the world is mostly lactose intolerant.
Don't really know how accurate this map is though. I'm surprised to see Somalia as being highly intolerant with our history of being nomads who live off of our Camel milk and meat.
