“This notion of species as ‘natural kinds’ fits splendidly with creationist tenets of a pre-Darwinian age. Louis Agassiz even argued that species are God’s individual thoughts, made incarnate so that we might perceive both His majesty and His message. Species, Agassiz wrote, are ‘instituted by the Divine Intelligence as the categories of his mode of thinking.’ But how could a division of the organic world into discrete entities be justified by an evolutionary theory that proclaimed ceaseless change as the fundamental fact of nature?”

Genesis 1:25 And God made the beast of the earth according to its kind, cattle according to its kind, and everything that creeps on the earth according to its kind. And God saw that it was good.
