Promissory notes, genetic clocks, and epigenetic outcomes

I respond to three continuing commentaries on Beyond modularity, two concerning the representational redescription (RR) framework and its attempts to account for the growing flexibility of human intelligence, and one relating to the putative mysteries of developmental timing. I discuss misunderstandings about the RR framework as well as some of its shortcomings. I strongly reject the notion of a genetic clock and go on to argue for epigenetic outcomes in which genes and environment interact during the protracted period of postnatal brain development.
