Archaeopteryx, a fossil discovered in the Jurassic rock layers of Germany, is about 150 million years old. It had feathers and wings, but it also had features commonly found in dinosaurs, like a long bony tail, claws on its fingers, and teeth in a jaw without a beak. Often considered the first bird, Archaeopteryx has long fascinated scientists who have debated how it could fly. A recent study has offered new insights into this mystery, shedding light on how this ancient creature might have taken flight. According to the study, Archaeopteryx likely used a different method to get airborne compared to modern birds. Researchers compared its anatomy to that of today's birds and found that it lacked the strong flight muscles and a keeled sternum — a feature that allows modern birds to power their wings effectively. This meant that Archaeopteryx couldn't have taken off with a single jump and then flapped into the air. Instead, it may have used multiple leg jumps to gain height and speed. The research team, led by Colin Palmer, who has spent over a decade studying flying reptiles called pterosaurs and a four-winged dinosaur named Microraptor, used a variety of tools to analyze how birds take off. They employed a force plate, a Raspberry Pi computer, high-speed cameras, and CT scans of bird skeletons to understand the mechanics of flight. They observed how modern birds like magpies, starlings, and crows use their legs as the main force for takeoff, and applied this knowledge to model Archaeopteryx's flight. The study suggests that Archaeopteryx could have used three consecutive jumps to gain enough speed to become airborne. Once in the air, its wings could have maintained a flight speed of about 7 meters per second. If it had added a flap during the jumps, it might have achieved this speed with just two leaps. This research reinforces the idea that Archaeopteryx is one of the earliest known transitional forms between dinosaurs and birds. Charles Darwin, in his 1859 book On the Origin of Species, predicted that fossils would eventually show the evolutionary links between major animal groups. Just a year after the book was published, a feather was found, and within two years, the nearly complete skeleton of Archaeopteryx was discovered. This fossil provided clear evidence linking birds to dinosaurs. Today, Archaeopteryx remains a key transitional species, representing the earliest known member of the bird lineage after it diverged from non-avian dinosaurs over 150 million years ago. While the possibility of an even earlier bird-like fossil still exists, none has been discovered yet, leaving Archaeopteryx as the first known bird.
