The Average Human Has 60 New Genetic Mutations 246

mcgrew pointed out a story about a new study that found the average person is born with 60 genetic mutations, very few of which involve weather manipulation or an amazing healing factor. This number was less than expected, leading the researchers to believe human evolution happens more slowly than previously thought. From the article: "Sixty mutations may sound like a lot, but according to the international team of geneticists behind the new research, it is actually fewer than expected. 'We had previously estimated that parents would contribute an average of 100 to 200 mistakes to their child,' Philip Awadalla, a geneticist at the University of Montreal who co-led the project, said in a press release. 'Our genetic study, the first of its kind, shows that actually much fewer mistakes, or mutations, are made.'

The Human Mutation 339

eldavojohn writes "Scientists in China have announced finding the gene that makes us human. The article explains that prior work has shown that humans, as compared with the great apes from which we diverged over 5 million years ago, have a longer form of a protein (type II neuropsin) located in the pre-frontal cortex of the brain. From the article: 'Gene sequencing revealed a mutation specific to humans that triggers a change in the splicing pattern of the neuropsin gene, creating a new splicing site and a longer protein. Introducing this mutation into chimpanzee DNA resulted in the creation of type II neuropsin. "Hence, the human-specific mutation is not only necessary but also sufficient in creating the novel splice form," the authors state.' The team is urging further analysis of the extra 45 amino acids in type II neuropsin since they believe that chain may cause protein structural and functional changes. The research didn't link anything with this protein, simply identifying it as a very distinct difference between us and our closest cousins."
