Teen drug abuse isn't limited to illicit drugs. Many OTC (over-the -counter) drugs, including cold remedies, laxatives, diet pills, and pain killers can cause serious health problems and even death.
From the development of the four-limbed body plan, the journey of animal life from water to land and the emergence of humans, Great Transformations focuses on the evolutionary changes that triggered the earth's incredible diversity.
Survival of the fittest: Is it raw competition, a level of cooperation indispensable to life, or both? Explore our own spiraling arms race with microorganisms - the only real threat to our existence - and trace the alarming spread of resistance among pathogens that cause disease.
The Mind's Big Bang - 60 minutes
Between 100,000 and 50,000 years ago, something happened that triggered a creative, technological and social explosion, allowing humans to dominate the planet. What forces may have contributed to the emergence of the modern human mind?
