Darwinius ()

Darwinius was a small primate that lived approximately 47 million years ago in what is now Germany. It inhabited a time when Europe was covered with dense tropical forests and modern groups of mammals were only beginning to take shape.

The remains of this remarkable creature were discovered in 1983 in an abandoned shale quarry near the village of Messel—a famous locality where nature preserved fossils with exceptional detail. The history of the find proved to be as notable as Darwinius itself. After excavation, the skeleton was divided into two parts and sold separately. Only decades later, in 2006, the Norwegian paleontologist Jørn Hurum happened to see one of the halves at an exhibition and succeeded in acquiring it for the Natural History Museum in Oslo for one million dollars.

Three years later, in 2009, both halves of the ancient skeleton were finally reunited through cooperation with the American owners of the second part. At that time, the discovery received widespread attention and the informal name «Ida»—in honor of the Norwegian scientist’s daughter. In the same year, marking the 200th anniversary of Charles Darwin’s birth, the animal was formally described and given the name Darwinius masillae—«Darwinius from Messel».

Ida’s body length was about 58 centimeters, and she was still a juvenile individual. Scientists estimate that an adult Darwinius may have been 15–20% larger. Its hind limbs were longer than the forelimbs, and its hands and feet resembled those of monkeys—with long digits and nails instead of claws. Such anatomy allowed agile movement along tree branches. It had forward-facing eyes that provided binocular vision and thus excellent depth perception. Its teeth indicate a herbivorous diet: Darwinius fed on leaves, seeds, and fruits.

Its long tail helped maintain balance during leaps, and its fur protected it from heat and rain in the warm Eocene forests. Owing to the exceptional preservation of the skeleton and soft tissues, Ida became one of the most thoroughly studied ancient primates.

However, contrary to initial expectations, Darwinius was not a direct ancestor of humans. Modern research shows that it is more closely related to strepsirrhine primates—lemurs and their relatives. Nevertheless, the discovery of Ida became an important link in understanding early primate evolution—a stage when, on the ancient branches of tropical trees, traits first began to form that would eventually lead to the emergence of ourselves.
