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.
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.
David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 2: Savannah) East Africa is a land which is constantly changing. To survive here, creatures must be able to deal with unpredictable twists and turns - wet turning to dry, feast to famine, cold to hot - no matter how hostile it becomes. From dense forests to snow capped peaks, steamy swamps and endless savannah, this unique and varied land is also a haven for life, supporting large animals in numbers found nowhere else on Earth. But away from the familiar, forever-travelling herds, there are a huge cast of other characters - lizards that steal flies from the faces of lions, vast dinosaur-like birds who stalk catfish through huge wetlands, and an eagle who risks everything on the arrival of ten million bats from a far off rainforest.
In which John Green and Hank Green teach you about how human primates moved out of Africa and turned Earth into a real-life Planet of the Apes. And the apes are people! John and Hank teach you about how humans evolved, and the sort of tricks they picked up along the way like complex tool use, big brains, and fighting. Learn more: http://www.bighistoryproject.com
Huge changes have swept across Arabia since the discovery of oil and the Arab relationship with nature has changed too. This is summed up by the changes to camel racing, now an ultra hi-tech sport. Arabia's animals now live alongside a very modern society but Arabia's people are using technology to protect nature: dugongs are fitted with satellite transmitters; hunting falcons chase down radio-controlled planes and the world's first carbon-neutral city is being built in the very heart of oil country.
