- Feeding by tourists compromises health of already-endangered iguanas, study findsFeeding wildlife is an increasingly common tourist activity, but a new study shows that already-imperilled iguanas are suffering further physiological problems as a result of being fed by tourists.
- First in-depth analysis of primate eating habitsFrom insect-munching tamarins to leaf-loving howler monkeys, researchers have compiled the most thorough review of primate eating habits to date.
- Discovery of partial skeleton suggests ruggedly built, tree-climbing human ancestorA human ancestor characterized by "robust" jaw and skull bones was a muscular creature and more adaptive to its environment than previously thought, scientists have discovered. Researchers found a partial skeleton dated to 1.34 million years (Paranthropus boisei) in north Tanzania. The bones suggest the creature was more ruggedly built than previou […]
- Hummingbird metabolism unique in burning glucose, fructose equallyHummingbird metabolism is a marvel of evolutionary engineering. These tiny birds can power all of their energetic hovering flight by burning the sugar contained in the floral nectar of their diet.
- New genetic research finds shark, human proteins stunningly similarDespite widespread fascination with sharks, the world’s oldest ocean predators have long been a genetic mystery. The first deep dive into a great white shark’s genetic code has fished up big surprises behind a design so effective it has barely changed since before dinosaurs roamed.
