Video - Evolution of life. Synopsis How come milk is popular and considered healthy in some parts of the world, but in other parts of the world it makes people sick?
Did some of us evolve to be able to digest milk? Scientists have found out that there is a specific gene involved, the Lactase gene. People with one version of the gene can digest milk, whereas people with another version cannot. Video - Evolution of life. Synopsis Viruses can evolve fast and sometimes adapt quickly to a new host species.
For example, an influenza virus that normally infects birds can become adapted to humans. The tobacco etch virus normally infects tobacco plants. Video - Evolution of life. Synopsis Did you know that beetles can read ant trails and snails smell like ant pupae?
These beetles and snails in the Malaysian rainforest depend on army ants for housing and food, but the army ants move frequently to new nest sites. This results in tens of thousands of ants marching together to find a new place to live. But if one looks carefully at the marching ants, one can see some surprising things! Volker Witte (LMU Munich) works on army ants in the rainforest near Kuala Lumpur.

Video - Evolution of life. Synopsis A young medical assistant is giving a nice presentation about the principles of evolution.
The genetic information of each living being is subject to modifications. Mutations can lead to bacterial resistance towards antibiotics. When in contact with the antibiotic, the resistant bacteria will be the only ones to survive, multiply, spread all over and finishing up to be a big problem for medicine.

Video - Evolution of life. Synopsis 4 billion years ago, asteroids, large blocks of ice and rocks racing through the solar system combined into planets.
Our heroine Piccolina, a water molecule inside a frozen meteorite, lands on our planet. As ice melts, H2O molecules like Piccolina become liquid water, the elixir of life.In water, Piccolina meets molecules of all sorts, linking, combining and getting more and more complex. Piccolina and complex molecules get trapped inside membrane made of fatty molecules. Thus evolves the first cell, the beginning of life...

Video - Evolution of life. Synopsis For many years, Norwegian fishermen have been fishing cod from the sea.
Fishing is usually done with nets that catch the large fish and allow the small ones to escape. But one day the large fish started to disappear, and this is bad for the fishing industry. Scientists try to find out what is going on. Did the fish evolve towards a smaller size, so that now they can escape from the fishermen's nets? Video - Evolution of life. Synopsis Curious by nature, the young Charles Darwin embarks on a voyage around the world as naturalist aboard the Beagle.
At the time he was not to know that it was to be the beginning of a sensational scientific breakthrough. For five years he collects, observes and annotates everything he discovers in the other worlds. Back in England, he continues to work tirelessly on his extensive collections and finally, 20 years later, he publishes the fruit of his work: "On the Origin of Species” - the volume which enables us to explain the emergence and the extinction of species by natural selection.
