If
Yes and no. I have great sympathy with Gould on exaption etc. I am not sure about the large brain. Without having had time to
pursue as much literature as I would like I have an intuitive leaning toward the Aquatic Ape Theory which would have an
arrangement of the larynx etc (for breathing control) that serendipitously, in fully evolved form, allowed a wide range of vocal
control . Add that to an upright posture and some propensity for throwing rocks at things and you kick of language and tool use an
environment conducive to large brain evolution

>If cultural changes themselves were a byproduct of a
ccomplex brain with lots of architectural space to
doodle with, maybe replication of cultural products or
mentifacts could be one such nonaptive byproduct and
thus make Blackmore's memetic drive hypothesis
unnecessary? Here the brain would already be big and
culture secondary a a result.>
If
I don't see a problem with some memetic drive and coevolution of brains artifacts and mentifacts, save that I would see mentifacts
as languaged into existence. I suspect verbal capability and stone throwing (Calvin) came before brain growth kicked in, but it is
speculation at this stage.

..Sorry for the hand-waving, but I'm just aproaching
this at the "just so" level without anything handy to
use as a good example. Due to Pinker/Chomsky language
might be out as something that can be explained away
by memes, but perhaps religion could be somewhere to
look for answers. >>
If
I am not sure abour Pinker / Chomsky. Where does the selection pressure for innate grammars etc come in if you do not have
verbalisation ability. If that kicks starts the process there is then a survival advatage in evolving brains with language
acquisition capability. How do you evolve religion without language? (See Price and Lord, 2002? Journal of Memetics for more on
religion as memetic)
I'll pas on the rest of your post if you don't mind. Too much for the time available
