Ten years after the establishment of the "Osaka Group for the Study of Dyna
mic Structures" (1987-1997) some of its founders and adherents "confess" wh
at they think about the achievements of structuralism in the decade and the
perspectives of the Group. Away from the geno-centric view of neo-Darwinis
m, the organism is reaffirmed as central entity in biology, either as expre
ssion of a morphogenetic field (with genotype as selector) or as a set of c
onventional rules governing the genotype. Structuralism also opposer to the
imperialism and arrogance implicit in the orthodox theory of evolution. (A
second group of five contributions, perhaps the last, is presented in this
issue. A first group of nine papers appeared in issue 91-1, 1998).
