4.1 Trilobites
Fossils are a glimpse into the distant past and fascinate young and old alike. This unit will introduce you to the explosion of evolution that took place during the Palaeozoic era. You will look at the many different types of creatures that existed at that time and how they managed to evolve to exist on land.

Next steps
The new discipline of astrobiology – that is, the science of searching for extraterrestrial life – is not only rapdly growing, but has also captured the public imagination. This unit examines the emergence of icy satellites of distant planets as potential sites of extraterrestrial life. Focussing on the case study of Jupiter's moon Europa, the unit looks at the potential for life there, and speculates on the ethics of searching for life elsewhere in the solar system.

Water is a natural resource that is vital for human survival and health, although only a tiny fraction of the Earth's supply is available to humans and terrestrial animals. In this unit we look at threats, such as pollution, to water's capacity to support life around the world.
4.1 Three approaches to global environmental change
Human societies have to take urgent action to end their dependences on fossil fuels. We have to alter the whole path of our development and decision making in order to make our societies both environmentally adaptable and sustainable. This unit takes on the task of trying to chart some of the ways in which it might be possible.
