Professor Brian Cox explores the globe to reveal how a few fundamental laws of science gave birth to the most complex and unique feature of the universe - life.
Suitable for: Teaching Biology at KS3 and KS4/GCSE in England, Wales and Northern Ireland and SQA National 3/4/5 in Scotland.
Bacteria and the development of an oxygen rich atmosphere. video
Professor Brian Cox explains how the Earth developed an oxygen rich atmosphere due to organisms called Cyanobacteria.
Conservation of energy. video
Professor Brian Cox explains the first law of thermodynamics. He describes how energy is always conserved, never created or destroyed.
How has life on Earth become so varied? video
Professor Brian Cox explores how life on Earth is so varied, despite us all being descended from one organism, known as LUCA. He examines how cosmic rays drive the mutations that create evolution.
Lemurs: Evolution and adaptation. video
Professor Brian Cox visits Madagascar to track down the rare aye-aye lemur, and see how it is perfectly adapted to suit its surroundings.
Jellyfish and photosynthesis. video
Professor Brian Cox sees photosynthesis in action, investigating a unique type of jellyfish that have evolved to carry algae within their bodies and feed off the glucose the plants create.

Professor Brian Cox describes the similarities between isotopes of water on comets and our planet and suggests that the water in the oceans may have come from asteroids.
The origins of life on Earth. video
Professor Brian Cox explains that in hydrothermal vents on the ocean floor, energy is released in the presence of organic molecules.
Evolution of hearing. video
Professor Brian Cox explains the evolution of the mammalian ear bones, the malleus, incus and stapes by using a flicker-book to show how the gill arches of jawless fish altered in size and function.
Evolution of sight. video
Professor Brian Cox shows the stages of the evolution of the eye, from a primitive light sensitive spot, to a complex mammalian eye.
Evolution of the senses. video
Professor Brian Cox compares the way that protists sense and react to their environment with the action potentials found in the nerves of more complex life.
Gravity, size and mass. video
An explanation of how forces including gravity affect organisms. Professor Brian Cox explains that as size doubles, mass increases by a factor of eight.
Size and heat. video
Professor Brian Cox explores the relationship between an organism's body size and its metabolic rate.
