Whenever a creationist is asked to define kinds we get examples instead of a definition. (Interestingly the number of species contained in a given example increases with the evolutionary distance from humans.)
So in the vain hope of getting a clearer picture of what a kind is I would like a creationist to assess a group that is less familiar; egg laying mammals. Perhaps through this exercise we can discern the objective properties creationists use to determine what is a kind.
In the order Monotremes there are two families; Ornithorhynchidae and Tachyglossidae (platypus and echidna). There is only one monotypic genus of platypus. There are two genera of echidna; Tachyglossus and Zaglossus. Tachyglossus has one species and Zaglossus has three.
So how many kinds? 1? 2? 3? 5? What objective properties do you use to work it out?
