The Thread of Life

What Darwin Never Knew

December 2009 •English

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?

Human By Chance?

January 2020 •English

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 Scientist, The Imposter and Stalin: How to Feed the People

July 2018 •French

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 Journey of Man: A Genetic Odyssey

January 2003 •English

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.

The Real Eve

April 2002 •English

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.

Inheriting Your Physical Traits

January 1970 •English

This educational film from 1970 traces the inheritance of traits such as sex, eye color, height, and weight, showing the role of chromosomes and genes in determining their development.

The Hunt for the Oldest DNA

February 2024 •English

Three million years ago, camels roamed through Greenland’s endless forests and our ancestors lived in the trees. It all came to an end with the Ice Ages. What died and what survived, as natural selection shaped the evolutionary tree during this epochal shift from hot to cold? Until now, scientists have known less about the natural world before the Ice Age than they did about the age of dinosaurs, which ended 64 million years ago. A new discovery is set to reveal this lost world, species by species. Led by Danish gene-hunter Eske Willerslev, a team of scientists for the first time in history is sequencing DNA from before the Ice Age. The picture that emerges is of a hot planet, when forests blanketed the Arctic and carbon levels matched those in our atmosphere today. Is this a portrait of our own climate future?

Mind of a Rampage Killer

February 2013 •English

Your Inner Fish

April 2014 •English

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.

Posthumans

February 2025 •French

Director Dominique Leclerc spent years depending on medical devices for her survival. Then, looking for alternative solutions, she entered the world of emerging technologies. Posthumans follows her as she meets with cyborgs, biohackers, and transhumanists who are trying to use these technologies to outsmart illness, aging—and even death. The documentary looks at pressing ethical and political questions that are sure to impact the future of our species.

And Man Created the Cow

November 2016 •French

10,000 years ago, the European forests were inhabited by huge cattle with protruding horns: the aurochs. Then man began to domesticate them and created the cow. By crossing species, he adapted the animals over time so that they increasingly met his needs and desires. Industrial livestock farming was born. From then on, beef cattle and dairy cows such as the Holstein cow were bred. Milk production tripled within a few decades. Today, the cow of the future is produced by artificial insemination. By selecting a few breeding bulls that are considered to be top bulls, rapid genetic progress is ensured.

Gregor Mendel

The Dark Gene

June 2015 •German

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.
