See the extraordinary wildlife and people of the Andes. Pumas hunt guanaco, shape-shifting frogs hide in remote cloud forests and the descendants of Inca build bridges of grass. The world’s driest desert, huge salt lakes and spectacular peaks are all found in the world’s longest mountain range.
This film explores why it pays to work as a team as it reveals some of the most captivating and awe-inspiring group parenting stories from the animal world. For most group-living species, living together means dividing the labour. From elephants taking part in hostage negotiations for their babies to banded mongoose all giving birth on the same day, female lions forming a sisterhood to see off interloping males and musk oxen rallying together to defend their calves from hungry wolves... it's truly amazing what some animal parents are prepared to do for the next generation!
This programme looks at the evolution of fish. They have developed a multitude of shapes, sizes and methods of propulsion and navigation. The sea squirt, the lancelet and the lamprey are given as examples of the earliest, simplest types. Then, about 400 million years ago, the first back-boned fish appeared. The Kimberley Ranges of Western Australia are, in fact, the remnants of a coral reef and the ancient seabed. There, Attenborough discovers fossils of the earliest fish to have developed jaws. These evolved into two shapes of creature with cartilaginous skeletons: wide ones (like rays and skates) and long ones (like sharks).
Thanks to new technologies combining genetics, ethology, geology and even particle physics, paleontologists can now recreate the missing branches of the tree of life. Now, paleontologists can show that there were far more feathered dinosaurs than previously believed.
The older a species, the better it is at adapting to change. From the ancient lineage of sharks, who've evolved into perfect predators, to the living fossil known as the bichir, get a closer look at some of nature's enduring evolutionary masters.
The story of how more than 220 dinosaur bones were found in the Argentinean desert, which were found to have come from a previously undiscovered species, which is the largest land dwelling animal known to have existed. David Attenborough visits the archaeological dig and a laboratory where the remains are being cleaned and analysed with lead scientist Dr Diego Pol and evolutionary biologist Ben Garrod, and meets animators, model-makers, paleontologists and anatomy experts who are working to reconstruct what the 37 metre-long creature would have looked like.
