A quarry site in Nevada carries the evolutionary history of a population of stickleback fish that resided there when it was a freshwater lake.
Corn was originally bred from the teosinte plant by native Mexican farmers. The morphologies of modern-day corn and teosinte plants are compared to illustrate how artificial selection can bring about dramatic changes in plants.
What does a stack of fruits and vegetables have to do with the theoretical advantages of sexual reproduction? Find out in this demonstration with student audience members and Dr. David Page.
The many forms of dogs that exist today were all created through selective breeding from the dog's ancestor, the wolf. In a span of less than 10,000 years, breeders have changed traits and body shapes of dogs by artificial selection-for example, emphasizing different aspects of hunting and...
The floor of a rift valley is prone to periodic floods that carry in fine silt--the sedimentary matter responsible for fossil formation.
These are some of the animal species Charles Darwin would have seen when he visited the Galapagos Islands.
Due to the delicate nature of fossils, a hardening chemical is dripped onto every fossil before it is removed from the soil.
Chimpanzees are capable of using rocks as tools to crack nuts for eating. But they don't appear to use sharp-edged tools.
African rift valleys were formed by the separation of tectonic plates. Water flows down to the valley floors, creating rivers and lakes.
At the end of the ice age, the retreating ice sheet created many new lakes, some of which were colonized by sticklebacks.
A brief introduction to how stickleback fossils are collected and used to study evolution. It also shows the students who attended the 2005 Holiday Lectures taking part in a fossil-collecting activity.
Prehistoric stone tools are classified into six broad technological modes by the level of sophistication and method of fabrication.
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.
Neil Shubin brought the fossil of Tiktaalik to his daughter’s first grade class to see what the students would make of it.
