In this month's feature article, the National Geographic suggests that a cluster of genes may be responsible for our desire to explore. Apparently, there is a common variant of a gene (DRD4-7R, if you want to know) that often pops up in studies of those who are exploring and pushing boundaries. It's possible that that gene, coupled with the right physical ability, tools, resources, and--here's what I love as a writer--imagination leads us not only to wonder what's around the river bend, but to go there. I love this important linkage with science, imagination, and wonder.
