The vividly colorful Japanese tiger beetle can be found in and around mountainside villages across Japan. Only a few centimeters in length, they sprint at high speed and catch prey such as ants using their massive jaws. With their dynamic hunting displays, they are literally "tiny terrors". Their larvae are no less fearful. From tiny holes in the ground they ambush passing insects, instantly pulling them in. Watch and be amazed at the hunting scenes of both adult and young.
For 10,000 years or more, humans created new plant varieties for food by trial and error and a touch of serendipity. Then 150 years ago, a new era began. Pioneer botanists unlocked the patterns found in different types of plants and opened the door to a new branch of science - plant genetics. They discovered what controlled the random colours of snapdragon petals and the strange colours found in wild maize. This was vital information. Some botanists even gave their lives to protect their collection of seeds. American wheat farmer Norman Borlaug was awarded the Nobel peace prize after he bred a new strain of wheat that lifted millions of people around the world out of starvation. Today, botanists believe advances in plant genetics hold the key to feeding the world's growing population.
This episode of the documentary series focuses on the new giants, the heavyweights of the dinosaur world. It is only in recent years that experts have unearthed the biggest dinosaurs that ever lived. One monster eclipsed all others; more than seven times as heavy as diplodocus was the immense argentinosaurus - a single backbone was bigger than a human. For years, these giants were considered immune to attack from any predator - until the discovery of mapusaurus, a new giant killer whose fate appeared to be inextricably linked to argentinosaurus.
Traveling is extremely arduous for microscopic sperm -- think of a human trying to swim in a pool made of...other humans.
