Hammerhead shark research suggests that the first hammerhead appeared abruptly some 20 million years ago. It’s aerodynamic head, or cephalofoil, is a unique design, not only providing lift while swimming, but a platform for a distributed sensor suite, complete with widely spaced eyes and an array of electromagnetic sensors providing triangulation with superior binocular vision and electromagnetic tracking of prey, detecting extremely weak electrical signals arising from molecules in their prey. Even evolutionists admit it is “remarkable.” Indeed, an abruptly appearing design that requires our smartest scientists even to understand. In addition to this, the newer hammerheads are smaller versions of that original hammerhead. These “incredible shrinking sharks” must have independently evolved from the ancestral lineage.
Abrupt appearances, astonishing designs, and independent repeated evolution. It is, as E.O. Wilson would say, a consilience of evidence.
