1860, archaeologists discovered a special dinosaur called Archaeopteryx, which lived in the late Jurassic and was about 0.5 meters tall. This dinosaur not only has wings covered with feathers by birds, but also has many characteristics that only dinosaurs have, which makes scientists wonder: Could birds have evolved from dinosaurs?
In 2000, archaeologists found some blood vessels in a Tyrannosaurus rex fossil. After comparison by scientists, they found that they are very similar to those of ostriches. This seems to explain the relationship between dinosaurs and birds to some extent.
A few years later, archaeologists discovered dinosaurs that were similar to birds, such as Near Bird Dragon, Xiaoting Dragon and Dawn Bird. After several years of research, biologists finally proved that birds evolved from dinosaurs!
Then the chickens, ducks and geese we eat are also evolved from dinosaurs.
Some scientists have also studied which animal tastes most similar to dinosaurs. The answer is chicken (do you think you are eating chicken stewed with mushrooms? No, you are eating stewed mushrooms with dinosaurs! )
You may ask again, there is a dinosaur called pterosaur, which also has wings. Did birds evolve from this dinosaur?
Don't! Don't! Don't! Your problem has its own problems. Although the name of pterosaur has the word "dragon", pterosaur is not a dinosaur, but at most it is just a "cousin" of dinosaur. Moreover, pterodactyl's wing structure is different from that of birds, which is composed of its fourth phalanx lengthened and covered with skin and muscle, which is more like a bat that is not a bird. Therefore, pterosaurs flew in different ways. Some scientists speculate that pterosaurs can't take off in situ like birds, but can only take off at high altitude or after run-up.
