William H. Calvin, book review of NEURAL DARWINISM in Science 1988 (Site not responding. Last check: 2007-11-03) |
 | | Darwinism is all about the copying success of patterns (typically DNA strings); here I outline a seconds-to-minutes competition between different spatiotemporal firing patterns in a multifunctional cortical workspace. |
 | | Darwinism is our baseline mechanism for creativity in nature; there may be others, but we know that darwinism's environment-dependent differential reproduction is capable of achieving new stable levels of complexity, shaping up a new species within millennia and, within a week or two, an antibody to fit a novel antigen. |
 | | Perhaps the archipelago of chimeric islands came later, allowing a Darwin Machine to help select among alternate ballistic movement schemata (as is handy when throwing in novel situations, rather than from a standard distance), with other spare-time uses of the same neural machinery then developing (multi-tasking, language, long-term planning, analogical reasoning). |
