Abstract: For many contemporary Christian theologians, evolutionary biology rules out any account of an Adam and Eve that would explain the origin of our species. In response, I propose that there are sound and robust reasons to think that human beings share an intrinsic essence that puts them into a natural kind. I also propose that our natural kind can be defined by our developmental capacity for language, which I suggest is necessarily linked to the capacity for abstract thought. Thus, it is still reasonable to trace the origins of our natural kind to an original individual. In my view, Adam was the first anatomically modern human to have evolved this capacity for hierarchical and non-linear language that allowed him to construct an abstract internal map of the world. He was the first speaking primate, the first rational animal.
