Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.
Documentary about living with an addict and grappling with the genetic propensity of becoming one.
After a woman's at-home DNA test reveals multiple half-siblings, she discovers a shocking scheme involving donor sperm and a popular fertility doctor.
Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?
A well-preserved mammoth carcass is found in the remote New Siberian Islands in the Arctic Ocean, opening up the possibility of a world-changing “Jurassic Park” moment in genetics.
The made-for-cable documentary film The Real Eve is predicated on the theory that the human race can be traced to a common ancestor. The mitochondrial DNA of one prehistoric woman, who lived in Africa, has according to this theory been passed down from generation to generation over a span of 150,000 years, supplying the "chemical energy" to all humankind.
If we compare ourselves with our genetically closest living relatives, the chimpanzees, we have few physical advantages. We are far weaker, cannot move nearly as fast, and do not have the same climbing capabilities. Instead, humans excel in areas such as architecture, religion, science, language, writing, art, culture, and ideas. These achievements are due to our larger brain that contain billions of neurons. It was the rapid growth of our brain, originating about 2 million years ago, that allowed us to be the predominant species of the world. What caused this rapid growth of our cerebral cortex? Researchers worldwide have asked this question for many years, but now there finally seems to be an answer.
The documentary tells two very different human fates in the 1920s Soviet Union. Nikolai Vavilov was a botanical genius, Trofim Lyssenko was an agronomist who made great promises and fake inventions. Each of them tried to solve the country's nutritional problem, but only one succeeded.
The film tells a very personal story from two perspectives: our protagonist is both doctor and patient. As a patient, he has struggled with recurring depression for years, and as a doctor he wants to find out why. The search for the origins of his illness leads him into the realm of his own genes and casts light on the fundamental changes facing modern society as a result of the tremendous progress being made in the field of genetic sequencing. Along the way, he meets a host of people – researchers, artists, visionaries – who have developed their own very individual approach to genetic coding and are drawing attention to the social significance of genetic technology. The film does not restrict itself to a scientific view of the subject but also makes use of artistic visions and more playful approaches to genetic blueprints.
How did your body become the complicated, quirky, amazing machine it is today? Anatomist Neil Shubin uncovers the answers in this 3-part science series that looks at human evolution. Using fossils, embryos and genes, he reveals how our bodies are the legacy of ancient fish, reptiles and primates — the ancestors you never knew were in your family tree.
Spared by cancer, diabetes and possibly Alzheimer’s, men and women of small stature are intriguing scientists that are trying to postpone age-related illnesses. What mechanisms protect these small Ecuadorian from certain illnesses? From Quito to Los Angeles, via Tel-Aviv, the film follows the revolutionary research, step-by-step, that is attempting to understand and prevent diseases such as cancer. And outlines ways to live in good health… for as long as possible.
