New Video – SURFACE: Detecting convergence with stepwise AIC

SURFACEIn Methods’ latest video, Travis Ingram gives a brief introduction to the new phylogenetic comparative method SURFACE. This method uses stepwise AIC to fit a series of stabilizing selection models to a phylogenetic tree and trait data, and to quantify the extent of convergent evolution toward the same selective regimes. The tutorial explains how SURFACE works, and then shows an example analysis in R.
