Shelf Life Video: Screening Biodiversity

Scientists at The American Museum of Natural History explain why managing biodiversity is a key component in managing endangered species. This video is another in the Shelf Life series from the American Museum of Natural History. Even though one and a half million species of organisms have already been named and described, they represent just a tiny portion of the biodiversity of our planet. Having a distinct genetic identity is important because more variation tends to be better in the face of the changing world. And when populations get small and isolated…

Life on Earth May Be Older than We Thought

Life on our planet could be at least one billion years older than previously thought, according to new geological research from the University of Washington. Nitrogen is a chemical element that is essential for building genes. Without plenty of nitrogen, life on the early Earth would have been scarce. Researchers looking at some of the planet’s oldest rocks have found evidence that organisms were already pulling nitrogen out of the air 3.2 billion years ago, and converting it in ways that could support larger communities of lifeforms. Finding Ancient Life…

Oldest Primates Lived in Trees

By Kate Stone A new study from the University of Florida suggests that humans’ earliest primate ancestor was a tree-dwelling creature. Named Purgatorius, scientists believe it looked like a cross between a squirrel and tree shrew, and weighed less than a deck of playing cards. This ancient animal was previously known only by its teeth. The shape of the teeth allowed paleontologists to determine the Purgatorius — estimated to have weighed about 3.5 ounces — ate insects and plants, but researchers knew little else about its lifestyle. With the discovery of…
