Houdini Honey Badgers Can Escape From Anywhere So half the Internet has seen the video about what total badasses honey badgers are (reminder at bottom for those who want a second look). But they don't just have attitude. As this clip from a BBC documentary reveals, they're also really smart. Wanted: Fit, Fearless Scientist for Huge Underground Find When Becca Peixotto was facing an exciting new anthropology gig, she did what any right-thinking applicant would do: She crawled under her bed. Her Ikea bed, to be precise. It wasn't fear. In fact, even considerable probing fails to detect any trace of fear in the 40-year-old Peixotto, despite her experience with such terror-inducing activities as hanging from cliffs, spending 22 days backpacking with a group of teenagers, and being interrogated on nationwide TV.

Nature adapts to Chernobyl Chernobyl: 28 years after disaster On April 26, Ukraine marks the 28th anniversary of the Chernobyl disaster, the worst nuclear accident in history. Take a look at haunting scenes from inside the exclusion zone. Darwin/Lamark court case By Don Mills This six to seven 40 minute period activity allows students to role play while learning theories of evolution. To start this activity have your students write their names on scrap pieces of paper. Read the list of roles to the class. After reading the roles to the class ask the members of the class interested in being the judge to place their names in a beaker then draw a name and return other names to their owners. Repeat this process for the bailiff, attorneys, and court reporters.

Homo erectus Homo erectus Where Lived: Northern, Eastern, and Southern Africa; Western Asia (Dmanisi, Republic of Georgia); East Asia (China and Indonesia) When Lived: Between about 1.89 million and 143,000 years ago Early African Homo erectus fossils (sometimes called Homo ergaster) are the oldest known early humans to have possessed modern human-like body proportions with relatively elongated legs and shorter arms compared to the size of the torso.

guppy The purpose of this activity is to analyze how guppy populations change over time. The simulation activity allows you to start with a pool of guppies and your choice of predators, you will be able to watch what happens to your guppy population and how the introduction of predators can affect the guppy's appearance. The simulation will help you understand what pressures drive guppy evolution. *Activity adapted from PBS -

This Face Changes the Human Story. But How? A trove of bones hidden deep within a South African cave represents a new species of human ancestor, scientists announced Thursday in the journal eLife. Homo naledi, as they call it, appears very primitive in some respects—it had a tiny brain, for instance, and apelike shoulders for climbing. But in other ways it looks remarkably like modern humans. When did it live? Where does it fit in the human family tree? Videos / What Was The Miller-Urey Experiment? - Stated Clearly Description This animation was sponsored by the Center for Chemical Evolution, NSF, and NASA: 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.

Videos / What is Chemical Evolution? - Stated Clearly Description Have you ever wondered how life first got started on Earth? So do scientists! Though the question has not yet been fully answered, a careful study of Chemical Evolution is beginning to shed light on this mystery. In this film you will learn what Chemical Evolution is, how it works, and how it is different from Biological Evolution. Explore Further
