Query: Misappropriating Darwin

The book disappoints. Factually, there are very powerful cases of non-human animal bonding that exceeds even so-called normal human bonding. Secondly, the author neglects to take seriously the 'argument from marginal cases'. So, for example, autistic children, senile and retarded adult humans and the like, are simply incapable of even the minimal bonding that the author believes inhabits 'normal' humans. The result, on parity of reasoning, is that these marginal humans deserve lesser moral treatment. This seems at odds with our considered moral beliefs; indeed, many of us would think that these humans deserve extra care and consideration. The book is rather philosophically naive and leaves obvious objections unaddressed.
