David Attenborough asks three key questions: how and why did Darwin come up with his theory of evolution? Why do we think he was right? And why is it more important now than ever before? David starts his journey in Darwin's home at Down House in Kent, where Darwin worried and puzzled over the origins of life. David goes back to his roots in Leicestershire, where he hunted for fossils as a child, and where another schoolboy unearthed a significant find in the 1950s. And he revisits Cambridge University, where both he and Darwin studied, and where many years later the DNA double helix was discovered, providing the foundations for genetics. At the end of his journey in the Natural History Museum in London, David concludes that Darwin's great insight revolutionised the way in which we see the world. We now understand why there are so many different species, and why they are distributed in the way they are. But above all, Darwin has shown us that we are not set apart from the natural world, and do not have dominion over it. We are subject to its laws and processes, as are all other animals on earth to which, indeed, we are related.

There are free and frank discussions between mums and daughters and decisions to go against medical advice. So does breaking with the norm and sticking to your guns pay off?

In the third episode of the series, the intricate social dynamics of the Ngogo chimpanzee community come to a head. Decades of growth and dominance have made this the largest known chimp group, but internal rivalries lead to a significant schism, with a faction of males breaking away to form their own group, the Westerners. Once comrades, these chimps now face each other as deadly enemies. The tension escalates with the mysterious death of Pork Pie, leaving the central chimps in a state of heightened alert and mourning, while leadership struggles and territorial disputes intensify within both factions.
As the Westerners grow bolder, driven by the likes of Richmond and the ambitious Rollins, they encroach further into central territory, setting the stage for an inevitable clash.

This episode masterfully captures the raw emotion and brutal reality of chimpanzee warfare, leaving viewers on edge as alliances are tested and the fight for dominance reaches a fever pitch.

Another year in the life of Diddly Squat Farm, run by Jeremy Clarkson, Britain's best-known but least-qualified amateur farmer. Season 2 of Clarkson’s Farm promises to be even better than the first as Clarkson and his rag tag group combat the public, the council, and the government.
In the first episode, Clarkson attempts to diversify his farm's revenue sources (having made only £144 in the previous year) in an effort to increase his profits. He decides that his primary way of doing this will be a new herd of cows and promptly purchases several of the animals. However, the timing of when they will bring in money and the necessity of building an enclosure for them causes problems for Jeremy and Charlie. Meanwhile, inspired by the success of the farm shop, Clarkson has the idea to open a restaurant in the abandoned lambing barn to sell his beef and lamb, but he must deal with the cost of converting the barn and getting approval from the local council.
