It was just another day of fishing at the local pier when a man unknowingly reeled in a fish thought to be extinct for 65 million years. This short video explains how scientists were surprised to discover that this 360 million year old...

The featured movie focuses on the ancestry of our four-footed friends. Find the fundamental pattern of their limbs and vertebrae in fossils of fish. After viewing, biology learners can enjoy interactive websites to zoom in on the...

The heartbreaking story of Alfred Wallace's loss of collected evidence opens this documentary about the development of the theory of evolution. You will find supportive resources to use with the movie in your biology class.

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

Clear up the confusion between natural selection and evolution with this cartoon. A hand draws diagrams and scenery as a voice narrates. This little feature is ideal for introducing these two concepts to beginning biologists.

Well, shiver me timbers! Biology pupils practice using the Hardy-Weinberg principle for computing change in gene frequency within a fictional population of pirates. The genetic trait being analyzed is the presence of sea legs, legs that...

The award for the most effective adaptation goes to the mimic octopus, a newly described species. The octopus can change its color, shape, and behavior to mimic flounder, lion fish, sea snakes, and more. 

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Examine exactly what is meant by natural selection, as well as how it works in nature and through the assistance of humans. Presented with fun graphics and simple narration, the complex topic of natural selection is clearly explained in...

Introduce the topic of evolution and natural selection with visuals, vocabulary, and historical perspective. Budding biologists can examine the evidence on their own by going through the presentation, or the teacher can present to the...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

What do dinosaurs and modern birds have in common? More than you may think. See how scientists figured out the evolutionary relationship between these seemingly disparate animals. Additionally, discover how and why the feather evolved...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Part two of this entertaining series looks at Darwin's visit to the Galapagos, his return home, and his determination to support his theories with evidence. What fun!

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

Evolution occurs on large and small scales, in both living organisms and viruses. By learning the pathway taken by pathogens such as the virus that causes dengue fever, scientists can get one step closer to understanding how to stop...

"Is this a good evolutionary adaptation, or is it going to lead us to being the shortest lived hominid species on planet earth?" Listen as Kenyan paleontologist Louise Leakey discusses our evolution from common ancestry and her work in...

It's Mr. Anderson, and he's ready to explain natural selection! Be excited, because he has the ability to make scientific biology and genetic functions in terms of natural selection make sense. With great examples and a clear and gentle...

Look here for a narrative approach to cells origins and discovery by microscopes. Though it is a slightly older clip, it contains some lovely footage of cells up close. Begin with prokaryotes and move onto eukaryotes and the differences...

ItÕs one of those big Ideas that changes our view of the world and our place in it. DarwinÕs observations lead him to believe that species, including man, change or evolve over time. This short video focuses on his reluctance to publish...

"What Darwin could not appreciate...is that there is a fundamental relationship between the intensity of ultraviolet radiation and skin pigmentation, and that skin pigmentation itself was a product of evolution." Viewers are provided...

A snowball earth would stay frozen once frozen; so what melted the ice? A manganese dioxide deposit gives some clue. One scientist focused on volcanic eruptions as contributing more oxygen into the air and warming the earth. This...
