Yes, at least as far as this paper is concerned and what it states as an incorrect interpretation of "origins of new traits". The authors state that it is _incorrect_ to think that "offspring may exhibit new beneficial traits even if the parents did not possess them." I thought that was the whole point of evolution, that offspring exhibit new (beneficial or detrimental) traits the parents did not possess. The only thing I can think to explain why it would be incorrect are a) equivocations on the words "trait" or "possess", b) specifics about the _timing_ of evolutionary relevant mutation, or c) an assertion that crossover is the salient operator not mutation. > On Fri, Jun 12, 2009 at 4:09 PM, glen e. p. ropella < > g...@agent-based-modeling.com> wrote: > >> [...] >> http://www.springerlink.com/content/2331741806807x22/fulltext.html >> >> Table 3, under the "Intuitive (incorrect) interpretation" of "Origins of >> New Traits" says: >> >> "Offspring may exhibit new beneficial traits even if the parents did not >> possess them." -- glen e. p. ropella, 971-222-9095, http://agent-based-modeling.com ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
