Episode Information

Over billions of years, evolution has found many different ways for living beings to move from one place to another. But why do creatures move around at all? The reason for this behaviour are the driving forces of nature. In every region of Earth, the conditions for life are changing all the time. Sunshine or rain, wind or thunderstorm, hail or snow, variable temperatures as well as differing durations of day and night: these ever-changing conditions are driving creatures, as these are always looking for a better life – mostly, it’s about more food and water, or about shelter against the weather, or predators.
