Researchers report finding fossil remains of a 'proto-dinosaur,' some 10 million years older than previously known.
Analysis of proteins found in a scrap of collagen from a 68-million-year-old Tyrannosaurus rex leg bone provides strong evidence for the idea that dinosaurs are the ancestors of modern-day birds.
Many scientists attribute the world's great extinction events to major catastrophes such as asteroid strikes and massive volcanic eruptions. We'll talk with researchers exploring an alternate theory -- that massive algal blooms led to mass extinctions.
Scientists are working to refine the dates for an ancient cosmic collision.

\tWith its heavy outer shell, weak vision, and primitive brain, the nautilus lacks much of the excitement of the more flashy and cunning cephalopods. Yet a series of experiments by evolutionary biologists Dr. Jennifer Basil and Robyn Crook involving fish juice, blue lights, and mazes dispels the notion that this ancient species is incapable of basic learning and throws into question the origins of cephalopods' intellectual prowess.
