A quarry site in Nevada carries the evolutionary history of a population of stickleback fish that resided there when it was a freshwater lake.
Fossilized dung beetle balls are part of a comprehensive fossil collection project to reconstruct the habitat of Ardipithecus ramidus.
Stone tools similar to those found at prehistoric archaeological sites can be made by fracturing rocks, a technique known as flintknapping.
The floor of a rift valley is prone to periodic floods that carry in fine silt--the sedimentary matter responsible for fossil formation.
Due to the delicate nature of fossils, a hardening chemical is dripped onto every fossil before it is removed from the soil.
Ms. Pepe talks about her experiences doing field work with the Shea lab as an undergraduate at Stony Brook University.
African rift valleys were formed by the separation of tectonic plates. Water flows down to the valley floors, creating rivers and lakes.
Dr. Shea discusses his early interest in anthropology, how field work has changed over the years, and his outside interests.
Prehistoric stone tools are classified into six broad technological modes by the level of sophistication and method of fabrication.
Where and when did humans arise? What distinguishes us from other species? Did our distant ancestors look and behave like us?
How reasoning and evidence are used to understand human evolution.
Stone tools are well-preserved evidence of past human activity.
The hominid fossil record of the past six million years gives us surprising insights into the path of human evolution.
How has the amazing diversity of plants and animals evolved? What can fossils, butterflies, and stickleback fish tell us about the deep common ancestry of all living forms?
How Darwin came to publish The Origin of Species, and examples of how quickly evolution can change a population.
The genetic mechanisms by which evolution occurs, and an overview of the evidence for evolutionary theory.
How and why butterflies and fruit flies got their spots, and the fossil record for human evolution.
Leading evolution educator Ken Miller discusses the controversy surrounding the teaching of evolution.
This virtual lab teaches skills of data collection and analysis to study evolutionary processes using stickleback fish and fossil specimens.
Comparing features of a 4.4-million-year-old fossil skeleton to those of human and chimpanzee skeletons sheds light on our evolutionary history.
Paleoanthropology provides an excellent example of the scientific process at work.
The following classroom-ready resources complement The Day the Mesozoic Died, which tells the story of the extraordinary detective work that led to the stunning discovery that an asteroid struck Earth 66 million years ago, triggering a mass extinction of animals, plants and even...
A short article by Dr. Sean B. Carroll detailing the discoveries covered in the film The Day The Mesozoic Died.
A worksheet that guides students through The Stickleback Evolution Virtual Lab. The virtual lab lets students learn firsthand the methods for analyzing body structure in stickleback collected from lakes and fossils recovered from a quarry. Students measure, record, and...
The poster from the 2011 Holiday Lectures on Science, Bones, Stones and Genes: The Origin of Modern Humans. It provides a unique look at the classic "tree of life" and features a timeline of various hominid fossils and their stone tool usage.
