Fossil Timekeepers
7: Fossil Timekeepers

Our planet's fossil record reveals that the natural cycles we take for granted today were previously quite different. Learn how biostratigraphy, sclerochronology, Carbon-14 dating, and other tools reveal a historic Earth with a day as short as six hours and a year as long as 455 days....

33 min
Fossils and the Shifting Crust
8: Fossils and the Shifting Crust

Why do we find life on Earth exactly where it is today? Why are some species found only in isolated pockets while others are spread across multiple continents? Learn what fossils tell us about our planet's exciting historic migrations-of flora, fauna, and the continents themselves....

Our Vast Troves of Microfossils
9: Our Vast Troves of Microfossils

When we think of fossils, we tend to visualize large shells or bones. Microfossils, though, can reveal a more complete and dynamic picture of the past, including some of the most ancient history of life on Earth and details of climate change over 100's of millions of years with a resolution just not possible from large "macro" fossils....

Ocean Fire and the Origin of Life
10: Ocean Fire and the Origin of Life

For centuries, scientists believed all life on earth was powered by the sun via photosynthesis. That was before ecosystems, powered by chemosythesis, were found at volcanic oceanic ridge systems. Paleontologists have now found examples fossilized vent systems over a billion years old and the life that lived around them. These exciting fossils and their modern equivalents may help us understa...

Arthropod Rule on Planet Earth
12: Arthropod Rule on Planet Earth

Arthropods live successfully all around the Earth today, but it was an extinct group of arthropods, the trilobites, that dominated the globe following the Cambrian explosion. With the benefits of exoskeletons and their well-developed eyes, trilobites were a significant presence in earth's oceans for 250 million years, evolving into more than 20,000 species with a variety of life styles....

Devonian Death and the Spread of Forests
13: Devonian Death and the Spread of Forests

Today we look at forests as a sign of a healthy biosphere. But is it possible that the earliest forestation of our planet-as plants became larger, developed seeds, roots, and wood and expanded away from the shoreline-could be responsible for mass extinction towards the end of the Devonian period?...

30 min
Life's Greatest Crisis: The Permian
14: Life's Greatest Crisis: The Permian

What could have caused the Permian mass extinction, when around 90 percent of all species became extinct in the geological blink of an eye? Learn what paleontology reveals about the cascading series of events that led to runaway global warming and the greatest catastrophe faced on earth since the evolution of complex life....

32 min
Life's Slow Recovery after the Permian
15: Life's Slow Recovery after the Permian

Although after most mass extinctions, the biosphere is well on its way to recovery within several hundred thousand years, recovery took many times longer after the Permian extinction. Eventually though, life adapted and diversified into a wide variety of exciting new plants and animals. Enter the dinosaurs....

Dinosaur Interpretations and Spinosaurus
16: Dinosaur Interpretations and Spinosaurus

Learn how a recent discovery might answer "Romer's Riddle" and give us a new picture of Spinosaurus, the largest carnivorous dinosaurs to have ever lived. With an elaborate sail on his back and an interpretation that this dinosaur may have been semi-aquatic, Spinosaurus is at the center of much debate in the paleontological community today....

Australia's Megafauna: Komodo Dragons
20: Australia's Megafauna: Komodo Dragons

Meet the Komodo dragon, a 200-pound lizard found on several relatively small Indonesian islands today. Paleontologists now know these specimens are a relic population of a lineage of giant monitor lizards once common in Australia. But exactly how did these animals make that trip? And how much longer is their species likely to survive?...

Mammoths, Mastodons, and the Quest to Clone
21: Mammoths, Mastodons, and the Quest to Clone

When the Mastodon became the first extinct species to be discovered, much that the Western world knew to be true-i.e., the Biblical description of the creation timeline-was suddenly called into question. Today, the Mastodon offers us another major ethical challenge: Would it be possible for scientists to use their DNA and "bring them back?"...

The Neanderthal among Us
23: The Neanderthal among Us

For years, we thought of Neanderthals as brutish, ignorant, distant cousins we could mostly ignore. Not any longer. As revealed by The Neanderthal Genome Project, modern humans and Neanderthals were sufficiently similar to have interbred and produced viable offspring. As much as 30 to 40 percent of the Neanderthal genome may be spread the human population today....
