Skeptic Check: Evolutionary Arms Race
from Big Picture Science · host Big Picture Science
It’s hard to imagine the twists and turns of evolution that gave rise to Homo Sapiens. After all, it required geologic time, and the existence of many long-gone species that were once close relatives. That may be one reason why – according to a recent poll – one-third of all Americans reject the theory of evolution. They prefer to believe that humans and other living organisms have existed in their current form since the beginning of time. But if you’ve ever been sick, you’ve been the victim of evolution on a very observable time scale. Nasty viruses and bacteria take full advantage of evolutionary forces to adapt to new hosts. And they can do it quickly. Discover how comparing the deadly 1918 flu virus with variants today may help us prevent the next pandemic. Also, while antibiotic resistance is threatening to become a major health crisis, better understanding of how bacteria evolve their defenses against our drugs may help us out. And the geneticist who sequenced the Neanderthal genome says yes, our hirsute neighbors co-mingled with humans. It’s Skeptic Check … but don’t take our word for it! Guests: • Svante Pääbo – Evolutionary geneticist, Max Planck Institute for Evolutionary Anthropology, author of Neanderthal Man: In Search of Lost Genomes • Ann Reid – – Molecular biologist, executive director of the National Center for Science Education, Oakland, California • Martin Blaser – Microbiologist, New York University School of Medicine, member of the National Academy of Sciences, author of Missing Microbes: How the Overuse of Antibiotics Is Fueling Our Modern Plagues • Gautam Dantas – Pathologist, immunologist, Center for Genome Sciences and Systems Biology, Washington University, Saint Louis First released March 31, 2014.
