Paleontology
Archaeopteryx
Archaeopteryx is a Late Jurassic feathered theropod from the Solnhofen Limestone of Bavaria, Germany, long regarded as a pivotal transitional fossil linking non-avian dinosaurs and birds. Known from exquisitely preserved specimens with flight feathers, teeth, and a long bony tail, it has been central to research on the origin of avian flight and the early evolution of the avian body plan.
Human Evolution
Human evolution is the lengthy process through which modern humans developed from early hominins over approximately six million years, characterized by significant anatomical and behavioral changes.
