It sometimes takes years and many mistakes to piece together an entire animal. Collins uses Anomalocaris as an example of the long complicated process. Several fossil pieces of Anomalocaris were originally identified as entirely...

A single location, the Burgess Shale, in the Canadian Rockies has revealed thousands of fossils that tell a story of an ancient explosion of animal life, called the Cambrian Explosion. [5:05]

Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization. [11:44]

"A scanning device most commonly seen in hospitals is reshaping the science of paleontology by allowing researchers to peer inside irreplaceable fossils without damaging them." Find out what scientists are now able to see that they've...

Jenny Clack visits a site with fossilized tracks of an early tetrapod. She and her assistant hypothesize about what the animal was doing around 370 million years ago. [8:22]

How did scientists figure out the age of the earth? Trace the history of Earth Science and the developments scientists made in determining the earth's geologic eras. Scientists asked such questions like, what's up with fossils? Are they...

Scientists have found a 300 million year old fossil shark ancestor with an unusual feature -- fossilized brain tissue within the creature's skull.

Researchers have found fossil remains of a species of snake that they say weighed 2500 pounds, and grew to 45 feet long.

This lesson will explain how fossils can be used to determine evolutionary relationships. It is 1 of 6 in the series titled "Fossils."

Party Rock Anthem has been fossilized! Get some facts about fossils with this fun music parody. [3:15]

In this video, Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...

Paul Andersen lists major evidence for the existence of evolution. He begins with a discussion of Charles Darwin and the evidence that he presented in the Origin of Species, including biogeography, fossils, and homologies. He also...

Paul Andersen describes pieces of evidence that Charles Darwin used to support the idea of evolution and his process of natural selection. He begins with the following evidence use in the Origin of Species; artificial selection,...

New fossil finds shake up the human family tree.

Like any great scientist, Charles Darwin didn't come to his ideas alone. We'll talk with biologist Sean Carroll about the flora, fauna, fossils, and scientists that helped prove Darwin was right.
