Elongated snake‐like bodies associated with limb reduction have evolved multiple times
throughout vertebrate history. Limb‐reduced squamates (lizards and snakes) account for the …

Many of the great morphologists of the nineteenth century marvelled at similarities between
the limbs of diverse species, and Charles Darwin noted these homologies as significant …

Loss of limbs evolved many times in squamate reptiles. Here we investigated the genomic
basis of convergent limb loss in reptiles. We sequenced the genomes of a closely related …

Gymnophthalmids are a diverse lineage of Neotropical lizards that present challenges in the
understanding of their phylogenetic relationships and biogeographic history. Using a …

Macroevolutionary analyses can identify patterns associated with the origin and
diversification of species. Here, we gathered currently available genetic and morphological …

Morphology is among the most important traits influencing the interaction of individual
animals with their environments. Fossoriality reflects this functional association between …

Alopoglossidae is a family of Neotropical lizards composed of 23 species allocated in two
genera (Alopoglossus and Ptychoglossus). There is a lack of knowledge about the …

Squamates exhibit a vast diversity of body plans, which directly determines habitat use and
preference. Here the skeleton of the sand‐swimmer burrower gymnophthalmid …

Much of the striking diversity of life on Earth has arisen from variations in the way that the
same molecules and networks operate during development to shape and pattern tissues …

Evolutionary tempo and mode summarize ancient and controversial subjects of theoretical
biology such as gradualism, convergence, contingence, trends, and entrenchment. We …
