Chimpanzees are capable of using rocks as tools to crack nuts for eating. But they don't appear to use sharp-edged tools.
At the end of the ice age, the retreating ice sheet created many new lakes, some of which were colonized by sticklebacks.
Finches discriminate between members of their own species and those of a closely related species based on song and appearance.
This animation features the anole lizards as an example of how a single species can split and multiply into many different species with distinct traits.
Dr. Elinor Karlsson discusses her work with dogs as a model organism for genomic studies.
The fins of the scalyhead sculpin are related to our arms.
This classroom experiment supports the film The Origin of Species: The Beak of the Finch. Students collect and analyze data to learn why even slight variations in beak size can make the difference between life and death.
The shape of our hands comes from tree-dwelling ancestors.
Infant lemurs hitch a ride through the forest by holding on to their mother’s tummy or riding piggyback.
The Lizard Evolution Virtual Lab was developed by a team of scientists, educators, graphic artists, and film makers to explore the evolution of the anole lizards in the Caribbean.
The richness and diversity of life raises two of the most profound questions in biology: How do new species form? And, why are there so many species?
This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are guided to sort the lizard species by appearance, then generate a phylogenetic tree using the lizards’ DNA sequences to evaluate whether species that appear similar are closely related...
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.
The following classroom-ready resources complement The Origin of Species: The Beak of the Finch. By following four decades of research on the finches of the Galápagos islands, the film illustrates how geography and ecology can drive the evolution of new species.
The following classroom-ready resources complement The Origin of Species: Lizards in an Evolutionary Tree. Research on the anole lizards is enriching our understanding of evolutionary processes, such as adaptation by natural selection, convergent evolution, and the formation of new...
