Parece que es uno de los escollos de la memética. Susan Blackmore propone para salvarlo no llevar demasiado lejos la analogia gen-meme, considerar que su parecido se acaba en que son replicantes sometidos a un algoritmo evolutivo y reservar el termino "lamarckiano" a los debates sobre evolucion biologica de las especies que se reproducen sexualmente. Para la evolucion cultural propone una distincion que parece mas util, entre mecanismos que "copian instrucciones" (una receta de cocina por escrito o una partitura musical: ejemplos no lamarckianos) y los que "copian el producto" (copiar una musica o una tonada de oido: ejemplo lamarckiano). saludos -- Miquel Vidal :: Using Debian GNU/Linux BarraPunto SysAdmin :: yonderboy en barrapunto.com http://barrapunto.com :: http://mi.barrapunto.com/yonderboy Key fingerprint = 9816 F967 FD3C A4AA DD67 0DF7 8CD0 6F1A F724 244F
