DESCRIPTION:Combining evolutionary developmental biology\, physics\, and c
 omputer science\, we investigate the emergence of both complexity and dive
 rsity of integumentary traits in vertebrates. More specifically\, we perfo
 rm descriptive and mechanistic analyses of morphogenesis and patterning of
  skin colour and skin appendages in reptiles and mammals. First\, I will s
 how that the scales on the face and jaws of crocodilians are not genetical
 ly-controlled developmental units and that their spatial patterning is gen
 erated through physical cracking of the skin. Second\, I will show that ra
 pid skin colour changes in chameleons are not caused by dispersion/aggrega
 tion of pigment-containing organelles but by the active tuning of an intra
 cellular 3D photonic structure. Third\, I will show that recent genomic ap
 proaches allow deciphering the genetic determinism and development of thes
 e traits of interest.
