A close-up view of sex, bug-style, as David Attenborough talks viewers through the different ways in which creepy-crawlies reproduce. Size matters for the minuscule male orb spider, creepily sneaking up on its intended and trying to mate without her noticing, while there's no rest for the lothario-like butterfly, which has plenty of notches on its proverbial bedpost. However, the harvestman spider has no use for sex at all, and reproduces by cloning itself.
A visit to arguably the most famous archipelago on Earth, the Galapagos. It's home to a myriad of bizarre and unique creatures, endemic to these islands - but how did they get here and what is the key to these extraordinary islands that allows them to thrive? The programme reveals that this key holds not just the secret to life here, but also to how Darwin was able to leave with the ideas that would revolutionise biology.
Forty miles north of Honduras, near the Bay Island of Roatan, is a spectacular and pristinely preserved coral atoll: the Mesoamerican Reef. Explore the abundant and diverse marine life, lush vegetation, and magnificent caves of this rare underwater wonder.
Losing a parent in the wild can be deadly for young animals, but these orphans got lucky when conservationists stepped in. Meet clouded leopard cub sisters taken in by the Nashville Zoo, a baby wombat raised in an artificial pouch at Tasmania's Bonorong Wildlife Sanctuary, and more.
Sophie looks at one skill in particular that seems to give humans an advantage over all other animals - our superior talent for language. She explores what language really is, and how close other animals come to having it. She considers the world of primates and the theory that some apes may communicate through sign language, and reveals how, even in the womb, humans start to practise making the mouth movements needed for speech. But language isn't just a power to combine words. Professor Scott explores how we convey information through the tone of voice, our accents and the pace and pitch of our speech. But in a world when we regularly talk to computers, she also shows why scientists need to develop machines that can understand the subtleties of our speech. Finally, she looks at language in this digital age and explores the role that emojis play.
