It's virtually impossible to imagine life without learning. We come into the world armed with little more than a bunch of primitive survival instincts, but it’s thanks to our ability to learn that we start adapting to the environment, going from helpless infants into semi-autonomous children before maturing into young adults. Still, when it comes to how we learn, most of us differ considerably at every stage in that process. Now scientists are learning more about that variation and what's behind it.
