The Big Brain Gene

ExE122 writes: Scientists have discovered what they believe is the reason behind the advanced evolution of the human brain. Research found that a certain gene underwent a vast mutation millions of years ago, allowing our brains to develop to the levels they are at now. From the article: "Reporting Wednesday in the online version of the British medical journal Nature, the scientists said they do not know exactly what the gene does but that it is active at a key time and place in embryonic development when the brain is growing at its fastest pace." This also gives evidence that our brains are still in the process of evolving today.
