TL;DR: The genome of the Komodo dragon Varanus komodoensis is sequences and genetic changes associated with its unique sensory, cardiovascular and muscular systems are revealed, suggesting that selective pressure altered haemostasis genes to help Komodo dragons evade the anticoagulant effects of their own saliva.

TL;DR: It is concluded that differentiated sex chromosomes were already present in the common ancestor of Anguimorpha living in the early Cretaceous or even in the Jurassic Period, placing anguimorphan sex chromosomes among the oldest known in vertebrates.

TL;DR: Results show that differences in the morphology of the chromosome pairs 5–8 can be attributed to intrachromosomal rearrangements, which led to transitions between acrocentric and metacentric chromosomes in both directions.

TL;DR: It is shown that the identification of sex chromosomes in the original report was based on the erroneous pairing of chromosome in the karyogram, causing over decades an error cascade regarding the inferences derived from the putative existence of female heterogamety in geoemydid turtles.

TL;DR: In this paper, the authors performed cytogenetic analysis in 16 species of chameleons from 8 genera covering the phylogenetic diversity of the family and also phylogenetic reconstruction of karyotype evolution in this group.
