Abstract

New proteins and modules have been invented throughout evolution. Gene “birth dates” in Caenorhabditis elegans range from the origins of cellular life through adaptation to a soil habitat. Possibly half are “metazoan” genes, having arisen sometime between the yeast-metazoan and nematode-chordate separations. These include basement membrane and cell adhesion molecules implicated in tissue organization. By contrast, epithelial surfaces facing the environment have specialized components invented within the nematode lineage. Moreover, interstitial matrices were likely elaborated within the vertebrate lineage. A strategy for concerted evolution of new gene families, as well as conservation of adaptive genes, may underlie the differences between heterochromatin and euchromatin.

3. . Orthology and paralogy were introduced over 30 years ago as phylogenetic terms to distinguish gene duplication from speciation. Interspecies orthologs were defined as any genes that diverged strictly after the speciation; all other interspecies homologs and vacuously intraspecies homologs are termed paralogs. Purely a cladistic relation orthology says nothing per se about the degree of structural or functional conservation postspeciation. In particular because protein genes and even regions within them diverge at widely different rates orthologs may differ from negligibly to significantly in sequence and modular organization.
