If I remember correctly, I was watching the Discovery Channel one day, and they were talking about some tribal women in Africa who had developed some type of immunity against AIDS/HIV. I can't find this info on the web yet! But I still remember them talking about studying these women, and there immune system in hopes to mimic their ability to fight this disease. I know I've heard of it. I was wonder if anybody else heard of this? This could be, if it is true, some proof of how evolution works, and someday these women will pass the gene that allows them to fight AIDS to their offspring, and possibly in the future, the people of Africa will be totally immune to the HIV virus.
