Look at the flying dinosaur robot - it will allow you to restore the evolution of the wings in birds

It is believed that modern birds descended from several species of dinosaurs, and a transitional species between them

Archeopteryx served.This crow-sized creature, which lived about 150 million years ago, combined features of birds and reptiles: along with wings and a beak, it also had sharp teeth and a tail. Scientists believe that Archeopteryx could not fully fly - it could only jump and soar like a pheasant. It is believed that the ability to soar has become a necessary element for full flight.

The researchers decided to test this hypothesis - theycreated a robot, the shape and movements of which repeat the shape of Caudipterix - a larger peacock-sized animal, which is the earliest known flightless dinosaur with wings.

The movement of flapping wings developed passively andnaturally, when the dinosaur ran on the ground. Although this movement could not lift the dinosaur into the air, we saw that wing flapping may have evolved before gliding.

Previously, engineers from Humboldt University andPolytechnic school of Lausanne using computer simulation and four-legged robot recreated the gait of one of the first reptiles on Earth - Orobates pabsti. She lived on our planet almost 260 million years ago.
