A unified theory of biology

From Torday and Rehan, Evolution, the Logic of Biology (NJ: John Wiley and Sons, 2017).

"One major tenet of contemporary evolutionary biology--that there are both proximate and ultimate causes in evolutionary biology--is threatened by viewing evolution as a continuum from a cellular, homeostatic perspective. If that precept, which Erst Mayr used as a canard to maintain the independence of biology from physics and chemistry, could be eliminated it would greatly aid in the advancement of evolution theory, moving it away from dichotomous mutation and selection toward a unified theory of biology" (139).
