Abstract
In this review, we briefly discuss genes involved in eye and leg development in Drosophila melanogaster and Vertebrates. The fact that these animals have many homologous genes and the ways these genes interact in their development is consistent with the concept of ‘deep homology’ and the hypotheses of a complex common ancestor of Bilateria, which had eyes and limbs. Nematode genomes contain most of the genes, which control eye and limb development in other animals. We show this is also true for Nematomorpha, though the sets of preserved genes are different in these taxa: ortholog of dpp/BMP was found in Nematomorpha, though Nematoda have just a paralogs of this gene. Both Nematoda and Nematomorpha lack orthologs of genes Ss, fng/Rfng, Cll, which regulate limbs development in other animals.
期刊介绍：
Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
