>Genome doesn't have sufficient capacity to specify every connection explicitly .. and can encode about 1GB of information (page 6)
but genome (raw DNA sequence) is only small part of much more complex and dynamic system, which includes regulatory networks, metabolic pathways, RNA interference, cell signalling networks and whatnot [0], surely the number of bits that can be encoded by this is much higher than GB, probably by many orders of magnitude. Genome is just a blueprint of machinery that creates another machinery.
This is not to take away from authors point (and complex systems can be created with simple rules and just a few bits) but innate structure itself can be very complex, I'm wondering if there are any neurophysiological studies showing evidence of a built-in universal grammar, Chomsky's old idea [1]
