Abstract

Atran proposes that humans have a unique, innate, domain-specific tendency to create taxonomies of biological kinds. We show that: (1) in ontogenesis, children develop a notion Atran claims to be innate; (2) what Atran claims is unique to biological kinds may be found in artifact kinds; and (3) although Atran proposes a domain-specific mental construct for biological rank, it can be explained in domain- general terms.
