Ela foi muito atenciosa. O artigo está em um livro bem estranho: Koslowsky, P., ed. 1999. Sociobiology and Bioeconomics: The Theory of Evolution in Biological and Economic Theory. Berlin/ New York: Springer.<BR/><BR/>Em resumo, ela propõe definir o gene como um processo e não como uma entidade. Outro bom artigo, em que ela discute brevemente suas idéias (e as idéias de outros) é: Griffiths & Neumann-Held, The many faces of the gene, Biosciences, 1999.<BR/><A HREF="http://web.mac.com/mullerianas/iWeb/Site%203/Movie%202_files/many%20faces%20gene-1.pdf" REL="nofollow">Many faces of the gene</A>Chicohttps://www.blogger.com/profile/00953286793822171241noreply@blogger.comtag:blogger.com,1999:blog-31775867.post-79215823006996559382007-05-30T10:57:00.000-07:002007-05-30T10:57:00.000-07:00donde se puede conseguir ese artículo?donde se puede conseguir ese artículo?A.

The gene is dead - Long live the gene! Conceptualizing genes in the constructionist way.<BR/><BR/>It's important to pay atention to this point, because many evo-devoists have reduced the problem of integrating evolution and development to research mutation in the "master regulatory genes"Chicohttps://www.blogger.com/profile/00953286793822171241noreply@blogger.com
