One of the most remarkable recent findings in developmental biology has been the colinear and homologous relationships shared between the Drusuphila HOM-C and vertebrate Hox homeobox gene complexes. These relationships pose the question of the functional significance of colincarity and its molecular

โฆ Synopsis
The discovery of homeobox genes in vertebrates may allow analysis of a basic problem in developmental neurobiology : how regional digerences in CNS organization are specified during development. This view is based on the roles defined for homologous genes in Drosophila development, and is supported by studies of the patterns of homeobox gene expression in vertebrate embryos. Homeobox genes comprise a multigene family, members of which are expressed in dixerent spatially restricted domains along the anteriorposterior axis of the CNS. These observations are consistent with homeobox genes having roles in the positional speciJication of CNS organization, and experimental tests of this should be forthcoming shortly.

In Drosophila, dorsal mesodermal specification is regulated by the homeobox genes tinman and bagpipe. Vertebrate homologs of tinman and bagpipe have been isolated in various species. Moreover, there are at least four different genes related to tinman in the vertebrate, which indicates that this gene
The gut of vertebrates exhibits a common anteroposterior regional differentiation. The role of homeobox genes in establishing this pattern is inferred by their sites of expression. It is suggested that the primary source of positional information is in the endoderm, which subsequently establishes a
Ever since Darwin there has been a history of debate on the tempo and mode of evolution. Is speciation a gradual process involving the accumulation of minute variations extant within a species, or is it rapid, the result of major organismal reorganization? Does one define a species on the basis of g
