Well he has his flashes of brilliance. I think his section on redundancy of neural coding from page 211-3 isn't so bad. He even uses this as a chance to present an alternative to Blackmore's memetic drive theory. He does point out that duplication of neural states allows for a diffuse nature, but then I see his casual dismissal of Lashlley's engram as an error of ommission since Lashley entertained a concept of reduplication that seems to dovetail with how Aunger is getting at his form if distributed representaion. Aunger points to a redundnacy of the genetic code, but I think he could have benefitted from incorpoaryion of Susumu Ohno's theories on duplication and divergence here.
I may be off my rocker on this, but I'm intuiting that
both Lashley's reduplication concept and Ohno's
evolution by gene duplication concept are both
relevant to what Aunger is arguing. He fails to
address Lashley sufficiently beyond casually
dismissing him and he doesn't even mention Ohno that I
can tell. Redundancy is an important concept to ponder
and I will give Aunger credit where it's due.
This section "Reasons for replicating" does stand out
as one of the better parts of his book. The rival
hypothesis he posits to Blackmore's theory is also
provocative here and shouldn't be overlooked.
He has many errors of commission in this book, but yes
there are some gems, even if they come with their own
Persian flaws of omission.

If a non-anthropologist were to write a book about anthopology that states that Tasmanians had TV sets but lost these after they migrated to Tasmania from Australia on jet skis (which they also lost in their tool box) or if someone were to discuss an out of America hypothesis that reverses the human trajectory across the land bridge into Asia, Europe and Africa, that would be a howler right? That's just about as bad as what he said about ribosomes and base pairing, especially given that he was presenting DNA replication as an example of his larger general view. His mistakes on *Aplysia* and Galton's relation to Darwin aren't quite that bad but add up.
