Protein sites present different amino acids during their evolution, whose number reflects the selective constraints operating on them. This evolutionary variability is strongly influenced by the structural properties of the site in the native structure, and it...

Background. Yunnanolepidoids constitute either the basal-most consecutive segments or the most primitive clade of antiarchs, a highly diversified jawed vertebrate group from the Silurian and Early Devonian periods. Although the general morphology of yunnanolepidoids...

The epigenome regulates the gene expression of all differentiated cells and indicates which specific genes must be transcribed. It is argued that the expression factors that act on specific genes of the somatic cell involved in a behavior also act on the transcription...

Background. The phylogenetic placement of Cretaceous marine turtles, especially Protostegidae, is still under debate among paleontologists. Whereas protostegids were traditionally thought to be situated within the clade of recent marine turtles (Chelonioidea),...

Single-cell RNA-seq is revolutionizing our understanding of cell type heterogeneity in many fields of biology, ranging from neuroscience to cancer to immunology. In Immunology, one of the main promises of this approach is the ability to define cell types as clusters...

Background: The accurate annotation of functional roles for newly sequenced genes of genomes is not a simple matter. Function is, of course, related to amino-acid sequence and to domain structure but not always in straightforward ways. Even where given functional...

The abyss is a homogeneous and barrier-free sediment habitat. At least that is what the text books say. Yet, at the same time we know that abyssal communities are locally highly diverse. It appears contradictory that a seafloor habitat free of barriers and poor...

Despite an estimated molecular divergence date of 40 million years (middle Eocene) between wombats and their closest living relative, the koala, the fossil record of wombats is poor. The two oldest described wombats, Nimbavombatus boodjamullensis and Rhizophascolonus...

Sclerochronology is presented as an approach to reconstruct, from linear growth records, environmental conditions. This was proposed by analogy with dendrochronology, but shells differ from trees since shells increase in size by terminal, instead of radial, growth....

Horizontal gene transfer has had major impacts on the biology of a wide range of organisms from antibiotic resistance in bacteria to adaptations to herbivory in arthropods. A growing body of literature shows that horizontal gene transfer (HGT) between non-animals...

The development of methods to estimate rates of speciation and extinction from time- calibrated phylogenies has revolutionized evolutionary biology by allowing researchers to correlate diversification rate shifts with causal ecological factors. A growing number...

Almost a decade ago, the sequencing of ancient DNA from archaic humans - Neanderthals and Denisovans - revealed that modern and archaic humans interbred at least twice during the Pleistocene. The field of human paleogenomics has now turned its attention towards...

A recent paper by Lau and Jacobs (2017, PeerJ) negatively contributes to a critical conservation problem in the Gulf of California—better regulation of fisheries in the Upper Gulf of California. The paper’s broader conclusions are not supported by the data presented,...

The Lepidoptera is one of the most widespread and recognisable insect orders. Due to their remarkable diversity, economic and ecological importance, moths and butterflies have been studied extensively over the last 200 years. More recently, the relationship between...

The study of biodiversity within the spatiotemporal continuum of evolution, e.g., studying local communities, population dynamics, or phylogenetic diversity, has been important to properly identify and describe the current biodiversity crisis. However, it has become...
