The squirrel family is one of the most widespread on earth, so what is the secret to their success? There are squirrels that can glide through the air, outwit rattlesnakes and survive the coldest temperatures of any mammal. We uncover the extraordinary abilities of these cheeky characters, putting their problem solving to the test on a specially designed assault course. We team up with some of the world's top squirrel scientists who are making groundbreaking discoveries - from the fox squirrel who can remember the location of 9,000 nuts to the grey squirrel whose tree-top leaps are the basis of new designs in robotics. We also see the world through the eyes of an orphan red squirrel called Billy, as he grows up and develops all the skills he will need to be released back to the wild. It is time to meet the animal family we should never underestimate - the super squirrels.
France is known for its delicious food and wines, great art and architecture and celebrated culture of all kinds. But there’s another side to this popular destination that is not as visible, its wild side. Deep in the French countryside, it is possible for the adventurous to spot brown bears, wild boar, griffon vultures or wolves.
In Herne Bay in Kent, Steve makes a jaw-dropping discovery of sharks teeth on the beach. Looking at how bad fatbergs are for the arteries of our seas. Plus we soar high over Mull with Sea eagles, and Chris meets a photographer who believes we have the best marine life in the world.
This instalment examines the earliest land vegetation and insects. The first plants, being devoid of stems, mainly comprised mosses and liverworts. Using both sexual and asexual methods of reproduction, they proliferated. Descended from segmented sea creatures, millipedes were among the first to take advantage of such a habitat and were quickly followed by other species. Without water to carry eggs, bodily contact between the sexes was now necessary. This was problematical for some hunters, such as spiders and scorpions, who developed courtship rituals to ensure that the female didn't eat the male.
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.
