One of the most exciting discoveries in the long history of fossil exploration is Tiktaalik, a creature with a mix of features common to fish and four-legged animals, or tetrapods.
Set against the restoration of war-torn Gorongosa National Park in Mozambique, The Guide tells the story of a young man from the local community who discovers a passion for science after meeting world-renowned biologist E.O. Wilson.
The disappearance of the dinosaurs at the end of the Cretaceous period posed one of the greatest, long-standing scientific mysteries. This three-act film tells the story of the extraordinary detective work that solved it.
The epic voyages of Darwin and Wallace led each to independently discover the natural origin of species and to formulate the theory of evolution by natural selection.
The Double Helix is the story of the scientists and evidence involved in one of the most important scientific quests of the 20th century: the discovery of the structure of DNA.
In the Caribbean islands, adaptation to several common habitats has led to a large adaptive radiation with interesting examples of convergent evolution.
Four decades of research on finch species that live only on the Galápagos Islands illuminate how species form and multiply.
Scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
In some parts of the world, there is an intimate connection between the infectious parasitic disease malaria and the genetic disease sickle cell anemia.
Follow human geneticist Spencer Wells, Director of the Genographic Project of the National Geographic Society, as he tracks down the genetic changes associated with the ability to digest lactose as adults, tracing the origin of the trait to less than 10,000 years ago, a time when some human...
The rock pocket mouse is a living example of Darwin’s process of natural selection.
After the end of the last ice age 10,000 years ago, populations of marine stickleback fish became stranded in freshwater lakes dotted throughout the Northern Hemisphere in places of natural beauty like Alaska and British Columbia. These remarkable little fish have adapted and thrive, living...
This animated short video illustrates the life of Alfred Russel Wallace, who independently formulated the theory of evolution by natural selection at the same time as Charles Darwin.
This animated feature celebrates 17th-century citizen-scientist Antonie van Leeuwenhoek, whose discoveries of microbes changed our view of the biological world.
