Despite genetic variance for traits under selection, among-trait genetic correlations that are antagonistic to the direction of selection limit adaptive evolution within these populations. Predicted rates of evolutionary response are much slower than the predicted rate of climate change.1 aEtterson, J.R.1 aShaw, R.G.  uhttp://knz.lternet.edu/content/constraint-adaptive-evolution-response-global-warming
