When studying how fossil hominids moved, researchers usually analyse the morphology of bones — which is crucial for understanding the evolution of bipedalism — focusing mainly on muscle insertion sites. However, the potential information of studying other types of soft tissue, such as joint ligaments, is often overlooked. Now, an article published in the journal Scientific Reports emphasizes the importance of studying the anatomy of the insertion points of the wrist ligaments to reconstruct the locomotor behaviour and manipulative dexterity of fossil hominids throughout human evolution.

Paleontologists working in a cave on the Caribbean island of Hispaniola have discovered the first-known instance of ancient bees nesting inside pre-existing fossil cavities.

Fossils of animal bones found in a cave contained dirt and sediment in their empty tooth sockets. A scientist realized that it wasn't just dirt-- he'd stumbled across the preserved nests of prehistoric bees that had laid their eggs in these bones. This is the first time that bees have been known to use bones or fossils as nests.

A new study reveals a critical link between seasonal seabird nesting and the movements of top marine predators in the remote Northwestern Hawaiian Islands. The research found that the annual summer arrival of fledgling seabirds at French Frigate Shoals concentrates tiger sharks in specific areas, forcing other species, including gray reef and Galapagos sharks, to drastically shift their own habitat use to avoid predation and competition.
