Our DNA is unusual. During the course of evolution, certain genes have been copied; these duplications are not found in the DNA of other animals. For more than a decade, neuroscientist Franck Polleux, PhD, has been exploring the significance of this. Working with colleagues in the Hillman, Miller and Bruno labs, Polleux's team has recently uncovered evidence linking one particular copied gene to our mental abilities. Explore this new discovery and get to know your genetic makeup a little better in this animation, covering work recently published in the scientific journal Nature.
