Mr. Carlson outlines the path that he took to becoming a graduate student in the White lab, including his experience as a chef.
Ms. Everhart recounts her fieldwork experiences as a member of the Shea lab and the results of her first flintknapping attempt.
Ms. Gomez explains her research in the Tishkoff lab and how it may help in understanding malaria resistance.
Ms. Pepe talks about her experiences doing field work with the Shea lab as an undergraduate at Stony Brook University.
Dr. Shea discusses his early interest in anthropology, how field work has changed over the years, and his outside interests.
Dr. Tishkoff explains how studying genetic diversity can shed light on modern-day diseases, such as diabetes and obesity.
Dr. White talks about his passion both for his fieldwork and for educating the scientists of tomorrow.
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.
Genetic evidence shows that humans evolved in Africa and continue to evolve.
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 humans perceive bitter taste, and the evolution of taste perception.
Second discussion in the 2011 Holiday Lectures on human evolution, on how to effectively report scientific results to the general public.
Prehistoric stone tools are classified into six broad technological modes by the level of sophistication and method of fabrication.
Chimpanzees are capable of using rocks as tools to crack nuts for eating. But they don't appear to use sharp-edged tools.
Fossilized dung beetle balls are part of a comprehensive fossil collection project to reconstruct the habitat of Ardipithecus ramidus.
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.
Stone tools similar to those found at prehistoric archaeological sites can be made by fracturing rocks, a technique known as flintknapping.
African rift valleys were formed by the separation of tectonic plates. Water flows down to the valley floors, creating rivers and lakes.
Dr. John Shea demonstrates the two main principles in the study of rock layers: superposition and association.
Fossils are extremely fragile. Scientists remove them in a protective layer of plaster and clean sand away one grain at a time.
The lactase enzyme is produced in the small intestine of infants. It digests lactose by breaking it into glucose and galactose.
Environmental and cultural factors can affect whether a new human mutation becomes common in a population.
