Marine ecosystems are rich in “omega-3” long-chain (C 20-24) polyunsaturated fatty acids
(LC-PUFA). Their production has been historically accepted to derive mostly from marine …

The recent increase in genomic data is revealing an unexpected perspective of gene loss as
a pervasive source of genetic variation that can cause adaptive phenotypic diversity. This …

Animal genomes show networks of deeply conserved gene linkages whose phylogenetic
scope and chromosomal context remain unclear. Here, we report chromosome-scale …

Although it is widely believed that early vertebrate evolution was shaped by ancient whole-
genome duplications, the number, timing and mechanism of these events remain elusive …

Ancient polyploidization events have had a lasting impact on vertebrate genome structure,
organization and function. Some key questions regarding the number of ancient …

Parasitic nematodes (roundworms) and platyhelminths (flatworms) cause debilitating
chronic infections of humans and animals, decimate crop production and are a major …

Abstract Background The Mediterranean mussel Mytilus galloprovincialis is an ecologically
and economically relevant edible marine bivalve, highly invasive and resilient to biotic and …

Coleoid cephalopods (octopus, squid and cuttlefish) are active, resourceful predators with a
rich behavioural repertoire. They have the largest nervous systems among the invertebrates …

Reconstructing the genomes of bilaterian ancestors is central to our understanding of animal
evolution, where knowledge from ancient and/or slow-evolving bilaterian lineages is critical …

There is currently little information about the evolution of gene clusters, genome
architectures and karyotypes in early branching animals. Slowly evolving anthozoan …
