Natural selection has been found to accelerate the population dynamic growth rate
While there is plenty of evidence that shows that evolutionary processes often operate on population dynamic time-scales (see reviews by Thompson, 1998; Hairston et al., 2005; Saccheri and Hanski, 2006; Schoener, 2011), direct empirical evidence for hyper-exponential growth is currently rather limited. But natural selection has been found to accelerate the population dynamic growth rate of aphids by up to 40% over few generations at low densities (Turcotte et al., 2011a,b).
