Squid, octopus, nautilus, and cuttlefish are unlike any other marine creatures. With brain, eyes, mouth, tentacles, and, for squid, jet-propulsion siphon clustered at one end of the body, the cephalopod design is so effective that most of these creatures successfully hunt fast-swimming fish for food. But was their body design engineered by a Creator or chanced upon by nature?

Interesting markings were recently found on a rock in Newfoundland. A study concluded that they were trails left by seafloor-dwelling animals around 565 million years ago. But such a find is difficult to reconcile with the evolutionary teaching that muscles, and therefore animal locomotion, did not evolve until much later.

A new species of chimaera found in Californian waters has been given a name. Chimaeras are bizarre cartilaginous fish with features that stand out among other fish. What also stands out is their lack of evolutionary change over supposed eons of evolutionary time.

The evolutionary story is one of constant change. It proposes that simpler life forms evolved into complicated organisms whose offspring branched out in ever more diverse directions. But the modern forms of some creatures are so similar to their ancestors’ fossils that it is clear they haven’t changed much at all. If some species diversified, why didn’t others?
