Donata Vercelli on Asthma Genes and the Environment


14:06 minutes (7.43 MB)

The DNA Files producer John Rieger talked with Dr. Donata Vercelli, Assistant Director of the Arizona Respiratory Center at the University of Arizona. Dr. Vercelli says that not only is asthma genetically complex, but that it also clearly shows evidence of genes that work differently based on the environment.

Rick Potts on Climate Change and Human Evolution

Program: 

20:29 minutes (11.73 MB)

In this interview from The DNA Files documentary “The Heat is On: Evolution in Action,” producer Adam Burke talks with Rick Potts, Director of the Human Origins Program and Curator of Anthropology at the National Museum of Natural History at the Smithsonian Institution. Potts talks about the revolutionary idea that global climate change was a driver of human evolution, as well as a driver of extinction of other hominids. Potts argues that Homo sapiens’ ability to use culture to adapt to a variety of environments and climates lead to our successful dispersal throughout the world. But what does our current influence on climate portend for our future success as a species?

The Search for the Fountain of Youth: Genetics of Aging & Longevity


57:13 minutes (26.22 MB)

In 221 bc, Emperor Qin Shi Huang, best known for building the Great Wall of China, searched for the "elixir of life." In 1513, Ponce de Leon traveled to what is now Florida in search of the Fountain of Youth. Today, researchers are still searching for the "fountain of youth," but they are turning to genetic tools, rather than foreign lands, to find it.

DNA and Evolution: Where Did We Come From? Where Did We Go?

Program: 

58:31 minutes (26.82 MB)

Peoples all over the world have developed origin stories to explain why we're here, who we are, and where we're going. Now, genetic researchers are beginning to write their own account of our origins, through the study of DNA. This program tells us how DNA may have come into existence and how genetic studies have contributed to evolution theories so far. And it explores the controversies raised by genetic research.
