- You don't seem to appreciate that biologists use not one type of "box"
- (category) but a number of categories applied hierarchically. Traditional
- levels of the hierarchy, in decreasing order of diversity, are: kingdom,
- phylum, class, order, family genus and species.
-
- It is not surprising the order Monotremata contains the Platypus and the
- Echidnas. An order is a high level category. They are however, placed in
- separate families. Even the two Echidna species are placed in separate genera.
-
- How do you suggest biologists deal with the million of species on the planet
- without placing them in categories? Why do you make assertions about complex
- subjects of which you apparently know very little?
