I was surfing yahoo's site and reading about doctors leaving Iraq for their safety,when I saw in the corner "Elsewhere on the web".It was a recent article about genetics that says we may be more different than we think. It's address is http://abcnews.go.com/Health/print?id=2673307. It goes on to say that the mutations,being added or deleted determine which illnesses we get and can also be used to comprehend why we are like our families.
