then that article is slipping my mind.
Based on [link|http://fp.bio.utk.edu/skeptic/Book_Reviews/gould-full_house.htm|http://fp.bio.utk.ed...ld-full_house.htm] I think I know which book to look in to see if he talks about the far more restricted herbivore example that I had in mind.
Furthermore even if Gould did talk about it, he is not always right. Or he might have been talking about a more general trend which this specific subtrend is an exception of. My recollection is that this was somewhat of a standard textbook example. For instance look on page 4 of [link|http://biosci.usc.edu/courses/2002-spring/documents/bisc313-Coevolution.pdf|http://biosci.usc.ed...3-Coevolution.pdf] to see it listed along with other standard exmples of coevolution. And [link|http://www-geology.ucdavis.edu/~GEL107/w02_cowen/coevolutionadv.html|http://www-geology.u...evolutionadv.html] gives me the following reference:
Radinsky, L. 1978. Evolution of brain size in carnivores and ungulates. American Naturalist 112, 815-831.
