Reptile scale paradigm: Evo-Devo, pattern formation and regeneration

Reptile scale paradigm: Evo-Devo, pattern formation and regeneration.

The purpose of this perspective is to highlight the merit of the reptile integument as an experimental model. Reptiles represent the first amniotes. From stem reptiles, extant reptiles, birds and mammals have evolved. Mammal hairs and feathers evolved from Therapsid and Sauropsid reptiles, respectively. The early reptilian integument had to adapt to the challenges of terrestrial life, developin...

The evo-devo comet.

In his inspiring book Ontogeny and Phylogeny (1977), the late Stephen J. Gould explained why develop mental biology and evolution, two essential domains of the life sciences, had diverged during the course of the twentieth century; both disciplines had to reach independently a platform of mutual understanding, a theoretical framework wherein concepts are understood and accepted by both parties....

Reconsidering regeneration in metazoans: an evo-devo approach

Regeneration of body structures is an ability widely but unevenly distributed amongst the animal kingdom. Understanding regenerative biology in metazoans means understanding the multiplicity of the cellular and molecular mechanisms that lead to the differentiation, morphogenesis and ultimately the development of a particular regenerating unit. In this manuscript we critically assess the evoluti...

Evo-devo discovers morphology

constructive points. A critical examination is made of FA’s strength and weaknesses in comparison with other biomarkers, and ways to improve FA as a bio-indicator are suggested. As a whole, Developmental Instability is a mature and balanced compilation of an important subject in biology, which is, after all, about half a century old. Michal Polak has managed to combine excellent contributions o...
