I don't know much about anything, but is it possible that scales evolved in
order to reduce surface evaporation in early amphibians moving to land?
They had to do this with their eggs, why not skin?
How do amphibians produce their mucous covering? Does their skin have pores
which could have been adpated to produce scales? In other words, does the
means (pores) already exist?
