All this information all over sudden for this poor Fool trying to unsuccessfully understand the universe!

Follow wsieber's link and look at the response linked to at the bottom of the page. The link *that correspondent gives is to a 38 page .pdf document that I have printed out and will read sometime. It should also be noted that the gentleman in wsieber's link is responding to a newspaper article; it won't be the first time the press has converted "a gene linked to..." into "a gene for...".

Still, I love all this new information for me to gobble up and attempt to digest. I am already churning stuff around in my brain and coming up with more questions. Particularly note that the gene discovered in humans is also present in mice.
