The first part explores how centuries of scientific and religious dogma were overturned by the earliest discoveries of the existence of cells, and how scientists came to realize that there was, literally, more to life than meets the eye.
Sophie explores the world of silent communication in the animal kingdom and the human world - showing how much we can actually say without ever opening our mouths or making a noise. She reveals how some species have harnessed bacteria to generate light and how light messages are used by insects and deep-sea fish for a range of reasons, including attracting prey. Exploring how body language communicates huge amounts about us and other species, Professor Scott shows why a dog's wagging tail does not always mean it is happy and how humans can tell a lot about someone's state of mind from their posture alone. She reveals why yawns and smiles are contagious and how this can play a key role in social bonding and cohesion.

While most of the series has focused on conflict, this episode is all about co-operation. The suitably named social spiders spin one enormous, 30m web for the whole colony, a queen bee rules her hive with a strict hierarchy and some green ants show great team spirit to help build a nest together. There are no broken societies here. David Attenborough shifts the focus to bugs that prefer cooperation rather than conflict. They include burrowing cockroaches, the suitably named social spiders - which share a 30-metre web.
In which John Green and Hank Green teach you about how human primates moved out of Africa and turned Earth into a real-life Planet of the Apes. And the apes are people! John and Hank teach you about how humans evolved, and the sort of tricks they picked up along the way like complex tool use, big brains, and fighting. Learn more: http://www.bighistoryproject.com

In the second episode, Iain discovers how flowers have transformed our planet. He journeys to the remote islands of the South Pacific to track down the earliest flowers. In the deserts of Africa and rainforests of Vietnam, he sees how they brought brilliant colour to the most barren landscapes and sculpted the earth itself. And he learns how they drove the evolution of all animals - kick-starting our human story.
It’s sexy time with the arthropods! This week David Attenborough takes a look at the courtship rituals of the creatures beneath our feet. But lovebugs won’t want to take tips from these bugs. The male Chilean rose tarantula, for instance, weaves a silk mat; deposits sperm on it, then sucks that sperm into a finger-like appendage near his mouth before he looks for a mate. Then there’s the gruesome, but surprisingly effective, coupling of praying mantis. The cinematography is as amazing as ever, catching the mating battles of tramp ants and providing luminescent footage of the courtship dance of Tanzanian red claw scorpions.
