On occasion I work for Mechanical Turk. I do HITs. HITs are human intelligence tasks that can't be done by artificial intelligence. I get paid a little now and then. Today I worked for AccessDNA. The questionnaire I filled out reminded me that I am a European Caucasian, my relatives had an aneurysm, colon cancer, anemia and depression, and I take a lot of meds. AccessDNA is a useful site for people planning pregnancies, finding out what they're going to die from, who their father is or if they are indeed a father, and stuff like that. There are lots of links for people who need help because of their genetic inheritance. I have also received a promise that I will be notified of DNA souvenirs, gifts, and so on when and if they become available. A report was generated on me, and I received the summary, which was frustrating and leaves me wondering if there was more. For some reason the file was corrupted and I had to open it in Appleworks.
But there was a link on that site that fascinated me. A scientist is sequencing Neanderthal DNA and so far he concludes that Neanderthal and modern man interbred. So Neanderthals probably contributed to our gene pool. That would explain a lot.
