Humanity Gene Found? 231
Banana_Republican writes "Nature is reporting that that multiple copies of a mystery gene may be what makes us human. It appears that humans have multiple carbon copies of a recently discovered gene that other primates lack. In particular, one sequence not so romantically or emotionally termed 'DUF1220' was mentioned . Humans carry 212 copies of DUF1220, whereas chimps have 37 copies, and monkeys have only 30 copies. Apparently the current thinking is that this gene is responsible for coding important areas of brain function."

Fantastic. Unfortunately, that seems to come from the same school of thought as my suggestion here: this gene is responsible for male pattern balding and fully erect bipedal motion.

TFA says that there is a gene that humans have more copies of than primates and that this gene makes a protein in the brain. They don't know what the protein does in the brain indeed they have no idea what having multiple copies of the gene does. Yet they reach the conclusion that this gene may be responsible for giving us our humanity.
All they seem to have is a weak correlation between the number of this gene and intelligence (which is arguable - I know some really dumb people) and as we've all learnt many times "Correlation does not imply causation."
IANAGS but I'd wait until there was some more evidence on offer.

"Scientists don't know what the gene does."
No, they know what the gene does, it codes for a protein. They don't know what this protein does.
Then they say that the protein is expressed all over, including the brain, so that means it may be involved in brain function.
For all they know it could be a structural protein, which is a better bet if it's expressed outside the brain.
Somehow I doubt that a single gene is responsible for humanity.
I try to be positive when I post, but what kind of morons do they have writing this stuff? And this is Nature magazine? How about some info on what sort of protein it is: Kinase? Carboxylase? Protease? How about some info on the expression levels instead of how many copies there are? There could be 1000 copies in our genome, but if the expression is low, it doesn't matter.
Guess I'll have to RTFP, where P=Paper.

How about they do a *lot* more research and then get back to us when they have more than "we found that humans have more copies of a 'mystery gene' that codes for proteins in the brain than a monkey"?!

If you RTFA (I know, I know, this is
But there are a couple of other notes I'd like to make in response to your post, which are really responses to lots of posts of this nature. First, this is not a weak correlation; 212 vs. 37 vs. 1 is a significant difference in almost any context, and yes, we've all known some really dumb people, but unless those people are severely retarded, they're still a hell of a lot smarter than the smartest chimp or monkey. Second, I really wish people would stop invoking "correlation does not imply causation" as a mantra. Yes, it's true, but it's also true that correlation implies correlation -- by which I mean that if there is a statistically significant correlation between two variables, then it is entirely reasonable to assume that there exists some connection between them, and to use this assumption as, at the very least, a basis for further investigation.
I think people are so used to misinterpretations of correlation (almost never by scientists, BTW) that they forget that it is still a powerful and useful tool. Actually, this is true of statistics in general. Yes, it's very easy to lie with statistics; it is somewhat harder, but entirely possible and fairly common, to use them to discover great truths.

Religious groups have previously tried to censor research and punish scientists who published views that would question their power. Fossil fuel lobbies tried to censor research into global warming, the environmental movement tried to stop research into nuclear power, and cigarette companies covered up research relating to smoking and health. Likewise, research into what makes us human and how we evolved could expose the mechanisms that make human races different. This is something that liberal and multicultural elites will not allow, even in the face of conclusive evidence.
