A new study suggests that spiders and their relatives may have originated in the ocean during the Cambrian era, based on fossilized brain structures of Mollisonia, an ancient arthropod, which resemble modern arachnids more than previously thought, challenging the idea that they evolved on land.
New biomechanical research challenges the notion that Anomalocaris canadensis was an apex predator during the Cambrian era. Using 3D reconstructions and biomechanical modeling, scientists found that its front appendages were not suited for catching hard prey like trilobites, suggesting it primarily fed on softer prey. This study highlights the complexity of Cambrian food webs and challenges previous assumptions about ancient marine ecosystems.
