The film looks at one of the most critical questions facing the world today-that of food security-and demonstrates the desperate need for common sense, solid information, and calm logical deliberation. Using the often angry and emotional controversy over genetically-modified foods as its entry point, Food Evolution shows how easily fear and misinformation can overwhelm objective, evidence-based analysis. Food Evolution takes the position that science and scientists hold the key to solving the food crisis. But whose science? In the GMO debate, both sides claim science is on their side. Who's right? How do we figure this out? What does this mean for the larger issues of food security, sustainability, and environmental well-being? Food Evolution seeks to answer these critically important questions.
We humans often like to think we're the end of the line when it comes to evolution. But if we rewind through our short time on Earth as a species, and the many changes that have occurred to us along the way, we find we're still very much a work in progress. Renowned geneticist and author Spencer Wells reveals how changes in our genetic code have fuelled major changes in our appearance and capabilities over time, and why scientists believe we're continuing to rapidly evolve today. By understanding these changes, we are better prepared for the future.
Alice Roberts explores the latest discoveries in the study of human origins, revealing the transformation that has been brought about in this field by genetics. Traditional Palaeoanthropology, based on fossils, is being transformed by advanced genome sequencing techniques. We now know that there were at least four other distinct species of human on the planet at the same time as us - some of them identified from astonishingly well-preserved DNA extracted from 50,000-year-old bones, others hinted at by archaic sections of DNA hidden in our modern genome. What's more, we now know that our ancestors met and interacted with these other humans, in ways that still have ramifications today. Alice uses these revelations to update our picture of the human family tree.
Our lifespan is increasing by 2.5 years every decade - and a third of all babies born today can expect to live to 100. But living longer can come at a cost. Old age itself brings with it a range of debilitating illnesses, many of which are the result of accumulating damage during our lifetime. Three diseases in particular have become the main killers in the developed world - cancer, heart disease and dementia. But a revolution in bio-medicine is now offering new hope for the treatment of these ailments, and the potential to extend our lives still further. Methods such as gene editing and stem cell therapies are transforming the way medicine can conquer disease today. "How to Live Longer" counts with the guide of the Nobel laureate Sir Paul Nurse, for whom the big question isn't just what science can do to fix our bodies and extend our lives, but whether it's right to use all the tools and techniques available.
Boy or girl? It’s the eternal question. But that question may have more than two answers. Science reveals the line between male and female is blurred. And the battle of the sexes is happening deep within our cells. Are there more than two sexes?
Death is life's greatest certainty. But that may be about to change. Scientists have discovered an immortal animal that may hold the secret of endless regeneration. They're on the brink of editing our DNA so that we can cure ageing like a disease. Or is dying necessary for the survival of our species?
