A team of French experts in paleoenvironments has discovered algae and several bits of marine life that are completely encased in amber, a hard substance thought to originate from hardened tree sap. Amber is renowned for preserving exquisitely detailed fossils, often of insects.

Sand and other sediments can be transported by rivers and floods, but what kind of forces—and how much water—would it take to move thousands of cubic miles of sand from one side of a continent to the other?

In a recent issue of the journal BioScience, ecologist Jeffrey Levinton of Stony Brook University, New York, offered a well-written review of the current status of the “Cambrian Explosion” hypothesis and presented at least two enigmas in evolutionary thinking.¹

Have “primitive fingers” really been discovered in a fossil fish?¹ Many fish, fossilized or live, show bone structure in their fins, and evolutionary scientists have believed this to be evidence that land creatures evolved from fish.
