Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model
organism for the study of generalized insect development, and an important pest of stored …

Many questions regarding evolution and ontogeny of the insect head remain open. Likewise,
the genetic basis of insect head development is poorly understood. Recently, 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 …

Background The heads of annelids (earthworms, polychaetes, and others) and arthropods (insects,
myriapods, spiders, and others) and the arthropod-related onychophorans (velvet …

Sexual reproduction is pervasive in animals and has led to the evolution of sexual dimorphism.
In most animals, males and females show marked differences in primary and secondary …

Background The red flour beetle Tribolium castaneum has emerged as an important model
organism for the study of gene function in development and physiology, for ecological and …
