This episode focuses on the Jurassic period, a time when the first giant killers stalked the Earth and lurked in the seas; a time when the slightest advantage meant the difference between life and death. In North America the iconic allosaurus, an ambush hunter with a lethal bite, dominated. Not even the heavily-armoured stegosaurus was safe from this killer, and incredible evidence reveals a glimpse of a vicious battle between these two giants. Life in Jurassic oceans was no easier; in 2008, a fossil was dug out of a frozen island high in the Arctic. It was a colossal marine reptile, twice as big as most ocean predators, at 15 metres long and weighing about 45 tonnes. This was Predator X. Its skull alone was nearly twice the size of a tyrannosaurus rex's, and its bite force unmatched by anything in the Jurassic seas. The balance of power between predator and prey is a fine one, as prey continually evolves different ways to avoid predators. But for the most successful and enduring predators, the battle to survive has always been tipped in their favour.
Every year, thousands of salmon make their way upstream along the nearly 2000-mile-long mighty Yukon River, desperate to reach spawning beds. Eagerly checking their progress is a host of hungry predators, from grizzly bears to bald eagles-all desperate to stock up on protein before the long winter months ahead.
What makes plants grow is a simple enough question, but the answer turns out to be one of the most complicated and fascinating stories in science and took over 300 years to unravel. Timothy Walker, director of the Oxford University Botanic Garden, reveals how the breakthroughs of Swedish botanist Carl Linnaeus, Chelsea gardener Phillip Miller and English naturalist John Ray created the science of botany. Between them these quirky, temperamental characters unlocked the mysteries of the plant kingdom and they began to glimpse a world where bigger, better and stronger plants could be created. Nurseryman Thomas Fairchild created the world's first artificial hybrid flower - an entirely new plant that didn't exist in nature. Today, botanists continue the search for new flowers, better crops and improved medicines to treat life-threatening diseases.
