When Giant Lemurs Ruled Madagascar
Just a few thousand years ago, the island of Madagascar was inhabited by giant lemurs. How did such a diverse group of primates evolve in the first place, and how did they help shape the unique environments of Madagascar? And how did...

The Evolutionary Epic Crash Course Big History 5
In which John Green, Hank Green, and Emily Graslie teach you about evolution. So, in the last 3.8 billion years, life on Earth has evolved from single-celled prokaryotes to the dizzying array of life we have today. So how did all this...

Natural Ecosystem Change
In this video Paul Andersen explains how the Earth's climate will natural change due to interactions between the Sun and Earth, volcanism, and plate tectonics. Species may go extinct leading to adaptive radiation or may move to a...

Unit 2 Review - Speciation
Paul Andersen reviews the major concepts within the second unit of the new AP Biology framework. He starts by describing how life is organized into three domains. He explains how the history of life on the planet is characterized by mass...

Speciation and Extinction
Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief...

Why Triassic Animals Were Just the Weirdest
The Triassic was full of creatures that look a lot like other, more modern species, even though they're not closely related at all. The reason for this has to do with how evolution works and with the timing of the Triassic itself: when...

Adaptive divergence
Or adaptive radiation, the divergence of life forms from a common ancestor, as they adapt to different environments. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning images and concise textual...

Understanding Speciation and Adaptive Radiation
This video explains the concept of speciation and how it occurs through natural selection and adaptation. It highlights the importance of isolation in promoting speciation, using the example of the Galapagos Islands and their endemic...

Speciation and Extinction
Are we, as some scientists theorize, in the midst of the sixth mass extinction? Scholars explore speciation through adaptive radiation and extinction with a video that uses the three-spines stickleback in Alaska, and its current...

Hhmi: Bio Interactive: The Origin of Species: Lizards in an Evolutionary Tree
In the Caribbean Islands, adaptation to several common habitats has led to a large adaptive radiation with interesting examples of convergent evolution. [17:45]
