This is also another occasion to remind ourselves that evolution is not a succession of “improvements” that occur in a straight line. Organisms hit upon different workarounds for the same and new physical challenges, depending on what is in their toolbox already. Hence co-option of genes, but also hence this elegant demonstration of a different solution to a particularly amphibian problem.

Thanks for the behind-the-scenes look!
