The mechanisms of biological evolution have always been, and still are, the subject of
intense debate and modeling. One of the main problems is how the genetic variability is …

Phenotypic plasticity is generally explained as the result of epigenetic mechanisms
modifying gene expression in response to changing environmental conditions. However, the …

Reptiles are notable for the extensive genomic diversity and species richness among
amniote classes, but there is nevertheless a need for detailed genome-scale studies …

Transposable elements (TEs) are DNA sequences that can insert elsewhere in the genome
and modify genome structure and gene regulation. The role of TEs in evolution is …

Abstract Chicken repeat 1 (CR1) retroposons are long interspersed elements (LINEs) that
are ubiquitous within amniote genomes and constitute the most abundant family of …

Squamates include more than 11,000 extant species of lizards, snakes, and
amphisbaenians, and display a dazzling diversity of phenotypes across their over 200 …

Sialidases are glycohydrolytic enzymes present from virus to mammals that remove sialic
acid from oligosaccharide chains. Four different sialidase forms are known in vertebrates …

Background The green anole lizard, Anolis carolinensis, is a key species for both laboratory
and field-based studies of evolutionary genetics, development, neurobiology, physiology …

Transposable elements (TEs) comprise a substantial portion of eukaryotic genomes. They
have the unique ability to integrate into new locations and serve as the main source of …

Hepadnaviridae are double-stranded DNA viruses that infect some species of birds and
mammals. This includes humans, where hepatitis B viruses (HBVs) are prevalent pathogens …
