Gap genes are involved in segment determination during the early development of the fruit
fly Drosophila melanogaster as well as in other insects. This review attempts to synthesize …

Most species on Earth are insects and thus, understanding their evolutionary relationships is
key to understanding the evolution of life. Insect relationships are increasingly well …

Background Phylogenetic and population genetic studies often deal with multiple sequence
alignments that require manipulation or processing steps such as sequence concatenation …

Phylogenies are usually dated by calibrating interior nodes against the fossil record. This
relies on indirect methods that, in the worst case, misrepresent the fossil information. Here …

We report here genome sequences and comparative analyses of three closely related
parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are …

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 …

Here we report the genome sequence of the honeybee Apis mellifera, a key model for social
behaviour and essential to global ecology through pollination. Compared with other …

A marine ecosystem model seeded with many phytoplankton types, whose physiological
traits were randomly assigned from ranges defined by field and laboratory data, generated …

Here we report the genome sequence of the honeybee Apis mellifera, a key model for social
behaviour and essential to global ecology through pollination. Compared with other …

Cryptochrome (CRY) proteins are components of the central circadian clockwork of
metazoans. Phylogenetic analyses show at least 2 rounds of gene duplication at the base of …
