David Attenborough travels to the Canadian Rockies where fossils document an explosion in animal diversity. Going on to Africa, Australia and Scotland, Attenborough discovers how animals evolved to conquer not only the oceans but also the land and air.
David Attenborough visits archaeological sites where fossils were found illustrating the origins of life on earth, in the ocean. For long, evolution worked very slow and species remained primitive, mostly single-cell, alter fractal. Only the invention of sexual reproduction kick-started genetic diversification.
As the first animal to be domesticated, pigeons have a story to tell. A drama filled, steeped-in-history, amazing story. Although they’ve faded into the background of city life, pigeons have made an incredible contribution to human history. For centuries, we relied on them for everything from food, to vital communications, to entertainment to modern day brain science. They deserve more respect! The ones you see on city streets today are the descendants of domestic birds. Their gritty urban lives are spent trying to evade all manner of perils…and… stay one step ahead of starvation, a constant threat. To survive where they’re not wanted, pigeons rely on a combination of charity from a few and their own incredible smarts…. In a series of fascinating experiments and carefully placed cameras, we take you inside their perilous world; in the air, on the street and in the nest. One of the first things to notice is just how incredibly smart they are.
Spy Pup is immersed in wild dog life to explore their maternal love, and Spy Penguin records the turbulent action of the mating season, as a male Adelie penguin falls victim to a pebble thief that ruins his chances of love for the season. Spy Tortoise and Spy Bushbaby keep watch on chimpanzees, while in perhaps the most moving scenes; Spy Monkey becomes the focus of attention for a troop of concerned langurs who believe the motionless camera-creature has died.
From penguins whose salt-removing eye glands shield them from the harsh ocean to caterpillars whose fake facial markings are meant to mimic a snake's, animals have evolved in amazing ways to see and be seen. Meet these creatures and see how they use eyes and illusions to their advantage.
What the Judean Desert lacks in size, it makes up for in extreme features: it's home to the lowest sea in the world, dazzling salt formations, and an array of plant and animal life. Watch the Arabian leopard, striped hyena, and other fascinating and resourceful creatures thrive against a backdrop of sun and sand.
Human mothers raise fetuses inside their wombs and breast feed their babies for a long time after birth. What made humans evolve so that we raise our children so affectionately? The latest research reveals an unexpected origin of mothers' affection toward their children. Scientists believe that our ancestors experienced unforeseen dramatic changes in DNA under threats of extinction. These DNA changes caused humans to be devoted to raising children. Learn about the scientific interpretation of the evolutionary roots of your affectionate bonds with your kids.
