Caption

Lead researcher Olivia Cope holds on to two aspen trees in the experimental plots. The two trees are the same age, but the larger tree is genetically predisposed to focus on growth, outcompeting its smaller neighbor. Over time, the faster-growing trees survived better, changing the genetic structure of the forest.
