Life Changing

  • Format:

SHORTLISTED FOR THE WAINWRIGHT PRIZE FOR WRITING ON GLOBAL CONSERVATION\n\nFor the last three billion years or so, life on Earth was shaped by natural forces. Evolution tended to happen slowly, with species crafted across millennia. Then, a few hundred thousand years ago, along came a bolshie, big-brained, bipedal primate we now call Homo sapiens, and with that, the Earth's natural history came to an abrupt end. We are now living through the post-natural phase, where humans have become the leading force shaping evolution.\n\nThis thought-provoking book considers the many ways that we've altered the DNA of living things and changed the fate of life on earth. We have carved chihuahuas from wolves and fancy chickens from jungle fowl. We've added spider genes to goats and coral genes to tropical fish. It's possible to buy genetically-modified pets, eat genetically-modified fish and watch cloned ponies thunder up and down the polo field.\n\nNow, as our global dominance grows, our influence extends far beyond these species. As we warm our world and radically reshape the biosphere, we affect the evolution of all living things, near and far, from the emergence of novel hybrids such as the pizzly bear, to the entirely new strains of animals and plants that are evolving at breakneck speed to cope with their altered environment.\n\nIn Life Changing, Helen introduces us to these post-natural creations and talks to the scientists who create, study and tend to them. At a time when the future of so many species is uncertain, we meet some of the conservationists seeking to steer evolution onto firmer footings with novel methods like the 'spermcopter', coral IVF and plans to release wild elephants into Denmark. Helen explores the changing relationship between humans and the natural world, and reveals how, with evidence-based thinking, humans can help life change for the better.

Helen Pilcher was a stand-up comedian for more than ten years, before the arrival of children meant she couldn't physically stay awake beyond 9pm. During this time, she performed at the Edinburgh comedy festival, at London's Comedy Store, and at various smoky pubs and clubs across Britain. She was a finalist for Jongleurs New Act of the Year (1998, 1999), the BBC New Stand Up Competition (1999) and Channel 4's So You Think You're Funny (1999). In 22, she teamed up with fellow comedian Timandra Harkness to write and performThe Comedy Research Project' a stand-up comedy show commissioned for the very first Cheltenham Science Festival. Unusually, Helen is also a professional science writer, with a PhD in stem-cell biology. She was formerly a journalist for Nature online, specialising in genetics; before that, she ran the Science in Society programme at the Royal Society, and before that, she worked as a senior scientist for a biotechnology company, engineering a series of human stem cell lines for transplantation into damaged human brains, this following on from her doctoral research into stem-cell therapy for Alzheimer's disease.
