From crowned lemurs to Bornean orangutans, the higher we move up the primate family tree, the closer their behavior mimics our own-especially when it comes to family and raising young. Peer into the astonishing adaptations that highlight the lengths primates will go to preserve and build family bonds.
A bold experiment to bring fierce African wild dogs back to Gorongosa National Park in Mozambique reveals how predators—and the fear they trigger—play a surprising and crucial role in keeping wild ecosystems healthy. Until recently, the impact of predators on ecosystems was thought to be simple: predators eat prey, keeping their populations in check. But more and more, ecologists are realizing that it’s not all about consumption. In fact, just the presence of predators can cause significant changes in behavior. Scientists call this the “Landscape of Fear,” and in Gorongosa, they are hoping to harness its effects to help bring an ecosystem back from the brink.
Two North American species have nearly vanished from their natural habitat in the course of the last century, due to a host of human and environmental factors. Can the elk and the wild turkey of Ontario be successfully brought back? Join the team of daring and ambitious scientists making it happen.
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.
