The second episode of the series immerses the viewer in a fascinating journey through the history of life on our planet, focusing on the evolution and adaptation of life in the seas. It begins billions of years ago, when the Earth was an inhospitable place and life was impossible on the surface due to a hostile environment. The documentary highlights how, beneath the waves, life began to flourish, protected from storms and other elements of nature. It addresses the development of photosynthesis by plankton and how this led to a significant change in the Earth's atmosphere, allowing the emergence of animal life.
This visually stunning narrative chronicles the evolution of various forms of marine life, from the earliest complex life forms to the appearance of the first fish and cephalopods. The documentary shows how marine life has influenced terrestrial life, emphasizing the impact of the 'greening' of planet Earth.

To survive, animals need somewhere to live, a place that provides the necessities of life, shelter from the elements and a refuge from enemies. Good homes are rare and competition can be intense – finding a home is one thing, but defending it is quite another.

The simple act of making an apple pie is extrapolated into the atoms and subatomic particles (electrons, protons, and neutrons) necessary. Many of the ingredients necessary are formed of chemical elements formed in the life and deaths of stars (such as our own Sun), resulting in massive red giants and supernovae or collapsing into white dwarfs, neutron stars, pulsars, and even black holes. These produce all sorts of phenomena, such as radioactivity, cosmic rays, and even the curving of spacetime by gravity. Cosmos Update mentions the supernova SN 1987A and neutrino astronomy.

The film, marking our first own production, embarks on an awe-inspiring journey, shedding light on one of science's most profound questions: How did life emerge from the non-living? With a focus on the intricate mechanisms that may have transformed simple molecules into the first microorganisms, this film explores the concept of a chemical evolution that meticulously selected increasingly complex molecules, eventually leading to the genesis of life. By delving into the pivotal role of RNA, viewers are invited to contemplate the plausibility of life spontaneously arising from the basic elements of the universe.
The documentary meticulously illustrates a potential pathway for the emergence of life, emphasizing the significance of ribozymes—RNA molecules with catalytic abilities—and their role in a prebiotic chemical evolution. The film posits a compelling argument for the natural processes that might have led to the formation of the first complex lipid vesicles, a critical step towards cellular life. By presenting a theory that bridges gaps in our understanding with scientific ingenuity, ‘The Origin of Life’ invites viewers on an intellectual adventure to discover the origins of existence itself.

In this episode, Michael demonstrates how our society is built on our search to find the answer to what makes up everything in the material world. This is a story that moves from the secret labs of the alchemists and their search for gold by the stone of the philosophers to the creation of the world's first synthetic dye - Purple - and onto the invention of the transistor. This quest may seem abstract and highly theoretical. Yet it has delivered the greatest impact on humanity. By trying to answer this question, scientists have created theories from elements to atoms, and the strange concepts of quantum physics that underpin our modern, technological world.
