Over a year ago I wrote a blog about the evolutionary oddity that is a peewee’s penchant to put everything (including dirt and cat poo) in his/her mouth. I was thoroughly convinced that this was some sort of evolutionary malfunction and that it is only by the grace of some sort of deity that we humans are still around.
Well it turns out that a baby’s fondness for putting anything (and everything) in his or her mouth is indeed an evolutionary function, not, as I had thought, a malfunction. There is a great article in the NY Times about it. The gist is that research has found that the goodness of dirt itself as well as all the heretofore thought nasties like bacteria, viruses and worms(!) stimulate the development of a healthy immune system. Therefore, back in the prehistoric day, it was the kids who weren’t eating dirt who didn’t make it and thus the genetic propensity for it. (The article doesn’t say this of course but heck it isn’t too much of a stretch now is it?)
So celebrate all ye dirt loving babes… that worm you just ate (eeewwwe) is actually good for you!
