The evolution of snakes involved dramatic modifications to the ancestral lizard body plan. Limb loss and elongation of the trunk are hallmarks of snakes, although convergent evolution of limb‐reduced and trunk‐elongated forms occurred multiple times in snake‐like lizards. Advanced snakes are completely limbless, but intermediate and basal snakes have retained rudiments of hindlimbs and pelvic girdles. Moreover, the snake fossil record indicates that complete legs were re‐acquired at least once… 
Snake-like limb loss in a Carboniferous amniote
TLDR
A new taxon of molgophid recumbirostran from the Carboniferous of Illinois, Nagini mazonense, suggests that the forelimb-first pattern of limb reduction that characterizes modern snakes also occurs early on in amniote evolution.
Hidden limbs in the “limbless skink” Brachymeles lukbani: developmental observations
TLDR
The observed pattern of ontogenetic reduction, leading to an externally limbless adult in which a limb rudiment is hidden and covered under the trunk skin, is a situation called cryptomelia and adds to the growing understanding of clade-specific patterns of limb reduction and the convergent evolution of limbless phenotypes through different developmental processes.
Evolution, Homology, and Development of Tetrapod Limb Muscles
TLDR
The methods, results, and controversies in the muscle reconstructions of early members of the amniote, mammalian, and lissamphibian lineages are reviewed, including recent attempts to reconstruct limb muscles inMembers of the tetrapod stem group.
Pigeon foot feathering reveals conserved limb identity networks
TLDR
Comparing pigeon limb bud transcriptomes to chicken, anole lizard, and mammalian datasets reveals a suite of predominantly low-level gene expression changes that are conserved across amniotes to regulate the identity of morphologically distinct limbs.
The convergent evolution of snake‐like forms by divergent evolutionary pathways in squamate reptiles *
TLDR
An important role of historical contingency as opposed to determinism is suggested in the convergent evolution of snake‐like body shapes in six clades of lizards, which showed that clades followed different evolutionary pathways.
Convergent evolution of elongate forms in craniates and of locomotion in elongate squamate reptiles.
TLDR
This is the first craniate-wide analysis of how many times elongate body forms have evolved, as well as rates of its evolution and reversion to a non-elongate form, and among the first evidence of locomotor convergence across distantly related, elongate species.
First evidence of convergent lifestyle signal in reptile skull roof microanatomy
TLDR
It is found that fossoriality evolved independently in 54 lepidosaur lineages and a highly compact skull roof, small skull diameter, elongate cranium, and low length ratio of frontal and parietal were repeatedly acquired in concert with a fossorial lifestyle.
Parallel evolution of apetalous lineages within the buttercup family (Ranunculaceae): Outward expansion of AGAMOUS1, rather than disruption of APETALA3-3.
TLDR
It is found that, compared with their close petalous relatives, naturally occurring apetalous taxa usually bear slightly larger numbers of stamens whereas the number of sepals remains largely unchanged, suggestive of petal-to-stamen rather than petal to-sepal transformations.
Hoxa13 regulates expression of common Hox target genes involved in cartilage development to coordinate the expansion of the autopodal anlage
TLDR
Results indicate that Hox13 transiently suspends the cartilage differentiation in the autopodal anlage via multiple pathways until establishing the paddle‐shaped structure required to generate five digits.

Developmental basis of limblessness and axial patterning in snakes
TLDR
It is shown that Hox gene expression domains are expanded along the body axis in python embryos, and that this can account for both the absence of forelimbs and the expansion of thoracic identity in the axial skeleton.

TLDR
This paper combines a molecular phylogeny for 27 species, morphometric data, and phylogenetic comparative methods to provide the first statistical phylogenetic tests of several long‐standing hypotheses for the evolution of snakelike body form, and finds no support for the hypothesized sequence going from body elongation to limb reduction to digit loss.
Reorganisation of Hoxd regulatory landscapes during the evolution of a snake-like body plan
TLDR
The results show that vertebrate morphological evolution likely involved extensive reorganisation at Hox loci, yet within a generally conserved regulatory framework, and show that snake and mouse orthologous enhancer sequences can display distinct expression specificities.
Evolution of the snake body form reveals homoplasy in amniote Hox gene function
TLDR
It is demonstrated that morphometric regional boundaries correspond to mapped gene expression domains in snakes, suggesting that their primaxial domain is patterned by a normally functional Hox code.
Developmental basis of evolutionary digit loss in the Australian lizard Hemiergis.
TLDR
A comparative analysis of expression of MSX and Distal-less proteins among embryos from different populations suggests an early role for SHH in specification of digit identity and later importance in maintaining cell proliferation and survival in Hemiergis.
Changes in Hox genes’ structure and function during the evolution of the squamate body plan
TLDR

A Cretaceous terrestrial snake with robust hindlimbs and a sacrum
TLDR
The new fossil from the Upper Cretaceous period of Patagonia fills an important gap in the evolutionary progression towards limblessness and retains several features associated with a subterranean or surface dwelling life that are also present in primitive extant snake lineages, supporting the hypothesis of a terrestrial rather than marine origin of snakes.
