 Whether such an account can indeed adequately explain taxonomic practice for species taxa is a question that can be left open here (see Ereshefsky &amp; Matthen 2005: 16ff.). By its own lights the account does not identify conditions for belonging to a species such as Homo sapiens (Samuels 2012: 25f.). Whether it enables the identification of factors that play the explanatory roles that the term “human nature” might be supposed to pick out is perhaps the most interesting question. Two ways in which an account of human nature might be developed from such a starting point have been sketched.
