Epithelial tissue — the sealed and polarized layer of cells that regulates transport of ions and solutes between the environment and the internal milieu — is a defining characteristic of the Eumetazoa. Sponges, the most ancient metazoan phylum [1], [2], are generally believed to lack true...

Background Gene conversion causes a non-reciprocal transfer of genetic information between similar sequences. Gene conversion can both homogenize genes and recruit point mutations thereby shaping the evolution of multigene families. In the rice genome, the large number of duplicated genes...

The nervous system is present in all but two animal phyla – one of them being Porifera, sponges. Sponges have no neurons and yet have organized behavior and finely tuned sensation. Furthermore, sponges have genes involved in the nervous system of other animals (informally called ‘neural’ genes)....

The theory of natural selection has advanced our understanding in every aspect of biological sciences, yet despite this seeming ubiquity, there remain some components that are not fully resolved. Natural selection predicts the “selfish” advancement of genes that are optimally suited for their...

Background Linkage disequilibrium (LD) maps can provide a wealth of information on specific marker-phenotype relationships, especially in areas of the genome where positional candidate genes with similar functions are located. A recently published high resolution radiation hybrid map of bovine...

Retroposition is widely found to play essential roles in origination of new mammalian and other animal genes. However, the scarcity of retrogenes in plants has led to the assumption that plant genomes rarely evolve new gene duplicates by retroposition, despite abundant retrotransposons in plants...

Homology is a natural kind term and a precise account of what homologyis has to come out of theories about the role of homologues in evolution anddevelopment. Definitions of homology are discussed with respect to the questionas to whether they are able to give a non-circular account of...

Background Insects constitute the vast majority of known species with their importance including biodiversity, agricultural, and human health concerns. It is likely that the successful adaptation of the Insecta clade depends on specific components in its proteome that give rise to specialized...
