A look at why a humpback whale would hold a diver hostage, how a colony of 1.5 million animals hide from the world in plain sight, and how a surprising stash of acorns could disrupt a whole town.
Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.
Following the success of Helen Macdonald's bestselling novel of the same name, H is for Hawk: A New Chapter is an intimate and personal journey. After the loss of her father, Helen trained the hardest bird in falconry, a goshawk. The cathartic experience helped her to grieve and now she is ready to do it again, but this time she hopes it will be her wings to somewhere new. In this beautiful and moving film, Helen trains a new bird and follows a wild goshawk family at the nest, getting closer than ever before to these fiery eyed birds of prey.
For nearly 4 billion years, the continents of Earth were a lifeless wasteland. But beneath the sea, our planet was teeming with life. Many strange creatures evolved, from eel-like conodonts to voracious cephalopods, until nearly all life was wiped out in our planet’s first mass extinction.
Life and Death explores the impact of Darwin’s ideas on our understanding of the meaning of extinction and the interconnections between all life on earth and the environment. Darwin learned many lessons from the giant fossils of extinct animals he found in Argentina and Chile. He eventually revealed to us the unpalatable truth that the logical conclusion to evolution is not perfection but extinction. The extinction of one species creates an environmental niche for new species to fill. Darwin’s theory also gives us vital knowledge we can use to help prolong the existence of our species by respecting the interconnections between all elements of the natural world and the environment. It’s a story in which Darwin’s ideas are taken up with great enthusiasm by his followers throughout the 20th century. But humanity misses one opportunity after another to acknowledge and reduce its destructive impact on the planet. As a result we have set in motion the sixth mass extinction of life on earth. And we are running out of time to do something about it by preserving ecological "hotspots" like certain rainforests which are some of the most productive cradles of evolution. This programme is a warning, but also a celebration, of the knowledge Charles Darwin gave us in his theory of evolution. It confirms that Darwin’s theory continues to inform our understanding of ourselves, our planet and the intricate interconnections between all life on earth.
