This episode is devoted to the evolution of reptiles. They are not as restricted as their amphibian ancestors, since they can survive in the hottest climates. The reason is their scaly, practically watertight skin. The scales protect the body from wear and tear and in the case of some species of lizard, such as the Australian thorny devil, serve to protect from attack. The horned iguana from the West Indies is also one of the most heavily armoured. The skin is rich in pigment cells, which provide effective means of camouflage, and the chameleon is a well-known example. Temperature control is important to reptiles: they cant generate body heat internally or sweat to keep cool.

The air we breathe, and all the food we eat, is created from water, sunlight, carbon dioxide and a few minerals. It sounds simple, but this process is one of the most fascinating and complicated in all of science, and without it there could be no life on earth. For centuries people believed that plants grew by eating soil. In the 17th century, pioneer botanists began to make the connection between the growth of a plant and the energy from the sun. They discovered how plants use water, sunlight and carbon dioxide to produce sugars - how, in fact, a plant grows. The process of photosynthesis is still at the heart of scientific research today, with universities across the world working hard to replicate in the lab what plants do with ruthless efficiency. Their goal is to produce a clean, limitless fuel and if they get it right it will change all our lives.

The series concludes by showcasing the work of scientists studying climate change to discover how exactly the environment is changing and its impact for all life on Earth. Glaciologist Alun Hubbard investigates Greenland's melting glaciers from within, while astronaut Jessica Meir describes witnessing forest fires across Europe from the international space station, and reflects on how changing weather patterns are interconnected.

Picture the last two hundred years without the publication of Darwin's "On The Origin of Species" -- how might the scientific conversation have developed? What were the influences in Victorian England during Darwin's youth, and how tenuous was his opportunity for sailing on the Beagle's voyage?
