Darwin's theory of biological evolution helps us understand how simple life forms can give rise to complex lifeforms, but how did the first reproducing creatures come about? The origin of life needs its own explanation.
Issues of genetics and DNA are constantly cropping up in the news from food production and health, to legal cases and ethics. We hear about DNA in movies like Jurassic Park and X-men, we learn bits and pieces about it from TV shows like Dexter and and CSI, but what exactly is DNA, and how does it work?
Biologists teach that all living things on Earth are related. Is there any solid evidence to back this claim? Join us as we explore the facts! We start with a close look at the origin of whales from land mammals, and then touch on the origins of several other critters, including our own species.
The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.

From the stealthy tarantula to the prehistoric Komodo dragon to the deceptive mosquito--one of the more prolific modern predators--killers come in all shapes and sizes. Join us as we examine the deadly adaptations of these cold-blooded culprits.
A look at how a dung beetle standing on its head can roll a ball in a straight line; if egrets ever regret hanging out next to hungry alligators; and what ghostly creature was caught on camera 3000 feet below the ocean's surface.
The jungles of the sacred city of Polonnaruwa in Sri Lanka are home to 33 identified troops of toque macaques and one man. This is the extraordinary story of Dr. Wolfgang Dittus, a scientist from the Smithsonian Institution who, over decades, has tracked and documented the lives of thousands of monkeys, revealing a complex society that is in many ways like our own. His journey is captured through his own words, footage he's taken over the course of 50 years, and his interactions with the scrappy, cheeky monkeys he's dedicated his life to.

A look at one of the most famous habitats on the planet, the Serengeti in East Africa, a vast grassland that is home to some of the greatest concentrations of herbivores on the continent. But what is the key to this exceptional grassland that allows such density and diversity?
