Evolutionary relevance of retinoic acid-induced craniofacial malformations
... treated skulls display combinations of characters present
in non-mammalian species arranged in a temporal sequence strongly reminiscent of the evolutionary sequence of gnathostomal jaws. They conclude with the hypothesis that modulation of a common regulatory signalling mechanism could be at the origin of c...
Origins of nervous system found in genes of sea sponge
