Darwinius is an extinct genus of primate that lived approximately 47 million years ago during the Eocene epoch. It is often referred to as a "missing link" in the evolution of modern primates, including humans. Fossils of Darwinius were discovered in Germany, providing valuable insights into early primate characteristics and behaviors. The most famous specimen, known as "Ida," is remarkably well-preserved and showcases features such as grasping hands and feet, which are indicative of tree-dwelling lifestyles. Darwinius helps scientists understand the evolutionary transition from early primates to more advanced forms, shedding light on the origins of the Primate order.
