▪ Abstract For 600 million years, the two best-understood metazoan species, the nematode
Caenorhabditis elegans and the fruit fly Drosophila melanogaster, have developed …

▪ Abstract More than 100 years have passed since Weismann first recognized the role of
germ cells in the continuity of a species. Today, it remains unclear how a germ cell is initially …

One central, and yet unsolved, question in evolutionary biology is the relationship between
the genetic variants segregating within species and the causes of morphological differences …

We report an extreme morphological difference between Drosophila sechellia and related
species of the pattern of hairs on first-instar larvae. On the dorsum of most species, the …

Eusociality has convergently evolved multiple times, but the genomic basis of caste-based
division of labor and degree to which independent origins of eusociality have utilized …

In Drosophila, as in mammals, epidermal differentiation is controlled by signalling cascades
that include Wnt proteins, and the ovo/shavenbaby (svb) family of zinc-finger transcription …

The recent determination and annotation of the entire euchromatic sequence of the
Drosophila melanogaster genome predicted the existence of about 13 600 different genes …

The Drosophila svb/ovo gene gives rise to differentially expressed transcripts encoding a
zinc finger protein. svb/ovo has two distinct genetic functions: shavenbaby (svb) is required …

Transcriptional control plays a key role in regulating epidermal proliferation and
differentiation. Although ample information has been obtained on how epidermal …

Evolution has created different castes of females in eusocial haplodiploids. The difference
between them lies in their functions and vulnerability but above all in their reproductive …
