HARRISON BERGERON by Kurt Vonnegut, Jr - harrison.pdf. 10-1259 United States v. Jones (01/23/2012) - 10-1259.pdf. National Science Foundation (NSF) Discoveries - Redefining Adaptation, the Study of How Populations Grow and Survive - US National Science Foundation (NSF) DiscoveryRedefining Adaptation, the Study of How Populations Grow and Survive Researcher also engages educators and students in an open forum June 27, 2013 How do organisms adapt over time? Do they evolve through a series of small beneficial steps as envisioned by Charles Darwin, or through a series of rare but large jumps?

Or through a combination of both? For example, "did a giraffe's neck get longer because there were thousands of mutations each resulting in a millimeter increase? " asks Christopher Marx, associate professor of organismic and evolutionary biology at Harvard University. Marx's research focuses on adaptation, the process by which populations improve in their ability to grow and survive. Understanding how adaptation works in smaller populations is important because many scenarios--from new infections to cancer--involve small numbers of cells. "If you change the population size, three things are supposed to happen," he says.
