My understanding is that twin studies have shown that intelligence is inherited. (Twin studies measure twins who were separated at birth, to distinguish between inherited and environmental effects.) I'm assuming that if intelligence is inherited, then it's encoded in chromosomes, and thus operated on by GAs. DS> Specifically, somatic cells, such as neurons, do not undergo DS> recombination. Can you be more specific? Do you mean that the components of individual cells don't undergo recombination? Do you mean that entire cells aren't recombined with other cells? What references are you using? And by the by, what was that "x" in your computational complexity table under the "Really Smart Systems" notestring?
