livingnlearning Posted October 28, 2011 Share Posted October 28, 2011 It's genetic-older genetics could not digest milk but newer Human 2.0 types developed the ability to digest milk past infanthood. :D I'm watching a Nova documentary on The Ice Man, the prehistoric man whose body was found in a glacier in Italy, and they say he was lactose intolerant and how the genetics worked on it. It's a super interesting show-my kids have been fascinated by it too. Quote Link to comment Share on other sites More sharing options...

livingnlearning Posted October 28, 2011 Author Share Posted October 28, 2011 What in the world is that? My 14 year old son calls anything new and updated a 2.0 model. Like Sister 2.0, dog 2.0, truck 2.0... just a little attempt at humor. Lactose tolerance was a genetic adaptation to farming and specifically, humans digesting milk past childhood.

livingnlearning Posted October 28, 2011 Author Share Posted October 28, 2011 I watched it on Wednesday and really enjoyed it! We did too except we initially started watching it while we were eating lunch. Had to record it to watch later as it wasn't really meal-time viewing material. :D Quote Link to comment Share on other sites More sharing options...
Carol in Cal. Posted October 28, 2011 Share Posted October 28, 2011 Yes, it's a mutation, which makes me a mutant, LOL! It's common among people with ancestors from Northern Europe, Kenya, and one other area in Africa--all of which had pastoral economies. Uncommon everywhere else.

kiana Posted October 28, 2011 Share Posted October 28, 2011 Yep. Actually, watching the spread of it is very interesting. A random mutation usually doesn't spread that widely unless it conveys some survival benefit (like sickle-cell in Africa actually protects against malaria in the heterozygous condition -- enough benefit that there's a strong selection for it genetically.)

Nakia Posted October 28, 2011 Share Posted October 28, 2011 I guess my genes missed the update. :glare: Quote Link to comment Share on other sites More sharing options...
mommymilkies Posted October 28, 2011 Share Posted October 28, 2011 Yikes. 2.0? You do realize 75% of the world is lactose intolerant, right? Does that make them an "older version"? Quote Link to comment Share on other sites More sharing options...
livingnlearning Posted October 29, 2011 Author Share Posted October 29, 2011 Oh brother. tough crowd. :glare: It was a joke, not a commentary on people's genetics. Sometimes this board is no fun at all. And actually, yeah, according to the show, the lactose intolerant genes are an older version. sorry.
