Is Archaeopteryx（始祖鸟）the Birds’ Direct Ancestor
We all learn at school that dinosaurs walked the earth for 165 million years until they became extinct-something that scientists believe was the result of a huge asteroid（小行星）crashing with our planet 65 million years ago. However,it is less known that one group of dinosaurs managed to survive, including the Archaeopteryx-a dinosaur which was half dinosaur, half bird.
In 1860 scientists found a fossilized feather which may have come from the Archaeopteryx dinosaur. The more exciting find was made in the following year,in 1861, when the first bones of Archaeopteryx were discovered.Just over a decade later,in 1974,another Archaeopteryx’s skeleton was found-this time even complete than the first one.
All three finds were made in Germany and it is also where the complete skeleton of Archaeopteryx can be seen-in the Humbold Museum in Berlin. The first skeleton was used as payment and given to a doctor, but luckily the Natural History Museum in London managed to purchase it and it can be found to this day. This dinosaur was given the name Archaeopteryx,which means “ancient” and “feather” in Greek. It is also sometimes referred to by its German name “Urvogel” which stands for “first bird”.
All the fossils of the Archaeopteryx dinosaur were invaluable to scientists. They noticed that, apart from the usual features expected in these types of dinosaurs, like teeth in the jaw,claws or a long bony tail, the fossils also showed marks that resembled feathers, which was a real thrill for the scientific community. Many people refused to believe that these fossils were genuine, but scientists started to think that this dinosaur might have been a link between dinosaurs and birds. However,this dinosaur had a long way to go before it would look like the birds we know nowadays. The question was, though, what Archaeopteryx needed feathers for it wasn’t for flying. The most obvious reason would be for body temperature control. However, it is also possible that their feathers, which developed from scales,played a role in their communication with one another.
Archaeopteryx wasn’t a large dinosaur compared to other,much larger ones,which were as heavy as 14 African elephants put together.With its 1 kilogram of weight and body length of 50 centimeters, the Archaeopteryx wasn’t much bigger that a pigeon.And just like these birds,Archaeopteryx probably exploited its plumage（羽毛）to attract females. It’s also possible that the feathers played an important role in providing shade for the eggs and young.
Scientists don’t know a lot about the Archaeopteryx’s diet, but they believe it mainly consisted of small reptiles（爬行动物）. It is also believed to have occasionally substituted these for small mammals or even insects.
Despite having feathers,Archaeopteryx did not fly in the sky, but some scientists think that the dinosaur attempted very short flight near the ground, for example, to hunt more effectively. Another reason would be to escape from danger and that is when their feathers must have been useful to help them blend into their surroundings.
It took a long time before dinosaurs could fly property and had the same features as birds, like a
beak（鸟嘴）without teeth. The change that helped them to become lighter,so that they could take off more easily,was a shorter tail.Once all the necessary changes had taken place,it was only a matter of time before dinosaur took to the sky.

In study after study, scientists are uncovering surprising new information about these mysterious mammals. Dolphins, they confirm, really do “talk” to each other, whistling “names” for themselves and others in their herd. They help one another when in trouble. Like bats they use sound waves to “see”,and can echolocate（凭回声定位）a first-size object in murky（昏暗的）water a football field away. Because of these and a wealth of other findings,many scientists now consider dolphins among the most intelligent animals on earth.
