Patrick Stewart narrates a global spectacle that probes oceans and scales mountains to explain our planet's past and present. What you don't know about your planet will thrill, amaze and even frighten you. The facts featured in this video are as startling as they are fascinating. Did you know that each year an average of 18,000 meteorites hit the earth; that it's 3,000 degrees Fahrenheit just four miles below you or that the top of Mount Everest was once part of the ocean floor? Take part in the exciting story of Earth: scoop molten lava from an active volcano. Explore the Moon with Apollo astronauts. Be present at the world's largest subsurface exploration. See Earth's oldest geological artifact - a 3.7 billion-year-old rock in Australia. Discover how Africa and South America split apart millions of years ago. Witness the devastating effects of an earthquake as it happens. Flee from deadly lightning-fast lava flows from an erupting volcano, and much more. Buckle up, you won't believe the power of this amazing earth!
The Earth might seem solid beneath our feet but five billion years ago there was no sign of the planet we call home. Instead there was only a new star and a cloud of dust in our solar system. Over millions of years, a series of violent changes led to the formation of our world and, eventually, the creation of life.
In this photorealistic CGI epic, see how a boiling ball of rock transformed into the blue planet we know today. Explore every aspect of our world; learn how water first arrived on Earth, discover the vital role oxygen played as life forms began to evolve, and find out how land mammals evolved into dinosaurs and other giant beasts, before becoming extinct 65 million years ago.
Cutting-edge imagery also reveals how humans first began to walk on two feet and looks into the future to see what may be in store for our home over the next five billion years.
Until recently the oldest, unchallenged evidence of human hunting came from a 400,000-year-old site in Germany the evidence came from marks left by spears on horse bones - horses were clearly being speared and their flesh eaten. but new Evidence from ancient butchery site in Tanzania shows early man used complex hunting techniques to ambush and kill antelopes, gazelles, wildebeest and other large animals at least two million years ago.- The discovery -- by anthropologist Professor Henry Bunn of Wisconsin University -- pushes back the definitive date for the beginning of systematic human hunting by hundreds of thousands of years.
Two million years ago, our human ancestors were small-brained apemen previously many scientists assumed the meat they butchered and ate had been gathered from animals that had died from natural causes or had been left behind by lions, leopards and other carnivores - "We know that humans ate meat two million years ago," said Bunn, speaking at the European Society for the study of Human Evolution (ESHE). "What was not clear was the source of that meat. However, we have compared the type of prey killed by lions and leopards today with the type of prey selected by humans in those days. This has shown that men and women could not have been taking kill from other animals or eating those that had died of natural causes. They were selecting and killing what they wanted."
Once our species got a taste for meat, it was provided with a dense, protein-rich source of energy. We no longer needed to invest internal resources on huge digestive tracts that were previously required to process vegetation and fruit, which are more difficult to digest. This new, energy-rich resource was then diverted inside our bodies and used to fuel our growing brains. over the next two million years our crania grew, producing species of humans with increasingly large brains
Video technology and science converge on an active volcano in Vanuatu, where explorer Sam Cossman operated camera-mounted drones to capture high-definition images of the spectacular yet dangerous Marum Crater. Cossman and his team piloted the drones over the 7.5-mile-wide (12-kilometer) caldera while confronting toxic gases and boiling lava. Although two drones succumbed to the harsh environment, the team was able to bring back video and photos that will help scientists learn more about the volcano and the life around it.
