However, the cerebral cortex has the lowest percentage of shared DHSs of the regions analyzed, possibly reflecting the greater extent of divergence of this structure between mice and men.
This might be due to the greater extent of divergence of this structure between mice and men than other CNS regions, like the cerebellum and retina.
Our working hypothesis proposes that the divergence of the gene structure of the PPN GHF5 gene family is associated with the expansion of the number of members from an ancient or early eukaryotic ancestral gene.
The divergence of the genomic structure in several ecdysozoan lineages compared to vertebrates and diploblastic animals has previously been described, and it seems that the FGFRL1 orthologues are no exception [ 20].
The diversity and morphology of male genitalia have been well documented in many insect taxa [ 1- 7], and most evolutionary biologists agree that sexual selection is responsible for driving the frequent and rapid divergence of these structures [ 6, 8- 11].
Thus this study indicates that, unlike geographic variation in patterns of human speech, acoustic divergence in the structure of the African green monkey bark is likely the result of phylogenetic distance rather than learning processes.
A number of studies have shown divergence in the structure of prophages encoding Stx genes in E. coli O157 H7, their insertion sites within the genome, and the type and level of toxin produced [ 22, 47, 50, 52, 53].
The present study examines the extent of conservation and divergence in the structure and evolution of Populus Aux/IAA and ARF gene families with respect to Arabidopsis and rice.
The amino-terminal segment differs significantly between species of the basal avian clade Palaeognathae (ratites, e.g. ostrich, and tinamous) and Neognathae (all other birds), indicating an early evolutionary divergence in the structure of EDCRP.
Divergence in the structure of p57KIP2 suggests functional specialisation in different species and may explain species-specific patterns of expression, subtle differences in the pathologies of human and mouse CDKN1C mutants [ 29], and the absence of imprinting of this gene in the tammar [ 14].
