Lets assume I. Kant would have became aware of Darwins theory of Evolution after writing his "Kritik der reinen Vernunft". How could the knowledge have affected his idea about the "ursprünglich synthetische Einheit der transzendentalen Apperzeption"? Especially how could it have affected his notion of transcendence? Since adaptation would suggest that our cognitive apparatus developed itself under influence of the phenomena. Or alternatively is there the possibility that he could maintain his approach?
(Please forgive my naive question, I am not an educated philosopher).
