An article on the Hub news page for Johns Hopkins University starts with a photo of a colorful glass knifefish, then poses a puzzle:
A quirk of nature has long baffled biologists: Why do animals push in directions that don't point toward their goal, like the side-to-side sashaying of a running lizard or cockroach? An engineer building a robot would likely avoid these movements because they seem wasteful. So why do animals behave this way? (Emphasis added.)
Stop right there. Ask how evolutionists and ID advocates would respond to this mystery. Evolutionists might think this is just leftovers from evolutionary "tinkering" or "cobbling," producing function good enough to permit survival. ID advocates might suspect a shrewder design than first meets the eye.
So what did the Johns Hopkins researchers learn from studying the apparently wasteful motions of the glass knifefish? In fact, they uncovered a superior design -- so good that it produces a functional benefit that has long challenged engineering wisdom:
