Cnidarians, the sister group to bilaterians, have a simple diffuse nervous system. This
morphological simplicity and their phylogenetic position make them a crucial group in the …

Background The duplication of genes can occur through various mechanisms and is thought
to make a major contribution to the evolutionary diversification of organisms. There is …

Draft genome sequences of non-bilaterian species have provided important insights into the
evolution of the metazoan gene repertoire. However, there is little information about the …

The tomato russet mite, Aculops lycopersici, is among the smallest animals on earth. It is a
worldwide pest on tomato and can potently suppress the host's natural resistance. We …

The formation of extraembryonic membranes (EEMs) contributes to the proper development
of many animals. In arthropods, the formation and function of EEMs have been studied best …

MicroRNAs are small (∼ 22 nt) noncoding RNAs that repress translation and therefore
regulate the production of proteins from specific target mRNAs. microRNAs have been found …

Tarantulas represent some of the heaviest and most famous spiders. However, there is little
information about the embryonic development of these spiders or their relatives (infraorder …

Organizers play important roles during the embryonic development of many animals. The
most famous example is the Spemann organizer that sets up embryonic axes in amphibian …

The venom contained within cnidarian nematocysts has a complex composition and holds
significant potential for biotechnological applications. In this context, one of the most …

Эволюция онтогенеза рассматривается как основная проблема эволюционной
