How Life Came to Land - Tierney Thys - Spiders and crustaceans, also known as arthropods, led the charge from water to land--now outnumbering all terrestrial animals. But what about arthropods makes them so adaptable to life on land? Marine biologist Tierney Thys, and Noé Sardet and Sharif Mirshak of the Plankton Chronicles Project, shows us a world of fascinating animals and their habitats.
Earliest Placental Mammal Ancestor - BBC News:Science and Environment - The creature that gave rise to all the placental mammals - a huge group that includes whales, elephants, dogs, bats and us - has at last been pinpointed.
Ideas about Human Evolution - Hank brings you some ideas, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development of many hominin species, now all extinct. Hank will introduce us to these species & the breakthroughs responsible for their development, and help us understand the awesome ways in which they led to us.

The Rise in Antibiotic Resistance - More than 70 years ago, Alexander Fleming discovered penicillin and set in motion a medical revolution. In 1943, penicillin was mass-produced and saved many wounded soldiers from death by bacterial infection. Yet even as we enjoy the benefits of antibiotics, their use promotes antibiotic resistance in bacteria. By confronting bacteria with antibiotics, we select for those that are resistant and change the course of their evolution. In fact, just three years after the first mass-production of penicillin, resistant bacteria began to appear. View the animation to learn more about the rise in antibiotic resistance.
What Causes Antibiotic Resistance? - Right now, you are inhabited by trillions of microorganisms. Many of these bacteria are harmless (or even helpful!), but there are a few strains of ‘super bacteria’ that are pretty nasty -- and they’re growing resistant to our antibiotics. Why is this happening? Kevin Wu details the evolution of this problem that presents a big challenge for the future of medicine.
Rise of the Superbugs - Are we entering the post-antibiotic era? Antibiotic-resistant bacteria are on the rise, with millions of infections reported every year and thousands of deaths. How does antibiotic resistance work? How did we get here?

Survival of the Sneakiest - Survival of the fittest" means that the strong succeed, and the weak fail, right? Well, often that's how it's portrayed, but the real story is a bit trickier. Let's take a closer look at what the crickets do...
Greatest Discoveries with Bill Nye: The Origin and Evolution of Life - Explore the history of paleontology, beginning at the site of an asteroid that may have brought about the demise of the dinosaurs. Visit Bob Ballard, who discovered new deep-sea life forms, and Douglas Erwin, who demonstrates how fossils provide a vivid snapshot of prehistoric life. Explore Linnaeus' 1735 species classification system and a dramatic re-creation of Darwin's development of his 19th-century theory of evolution.

Tree of Life Web Project - The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny).
