A creature preserved for 518 million years hints that the starfish family began with tentacles, challenging a long-standing picture of its earliest ancestor. Fossils discovered in southwestern China suggest that an animal called Yujingia glutenotunica lived close to the evolutionary roots of ambulacrarians, the group that includes starfish, sea urchins, and acorn worms. Its anatomy […]
These Fingernail-Sized Animals Are Moving Astonishing Amounts of California Beach Sand
A California beach can be reshaped overnight by creatures barely the size of a fingernail, with sand hoppers digging up to 110 pounds of sand per meter of shoreline each day. Researchers at UC Santa Barbara found that sand hoppers, tiny crustaceans that eat washed-up kelp, excavate extraordinary quantities of beach sand. Their study, published […]
NASA’s Bennu Samples Reveal a Surprising Origin Story
Instead of forming far out where comets took shape, Bennu may have emerged near the young solar system’s water-ice line, where Jupiter helped shape the mixture of dust that built the asteroid. Understanding exactly how the planets formed 4.5 billion years ago requires looking at material that has hardly changed since the solar system was […]
