問題詳情:
Dinosaurs ruled the planet for millions of years, and they are generally believed to have gone the reality is that modern versions of dinosaurs are all around us. Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.
The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.
According to Mark Norell, the director of the exhibit and an expert at the museum, it is based on new scientific evidence collected over the last two decades. "I think this is really going to shake up the way people think of dinosaurs “ Norell told reporters.” One could argue that we still live in the age of dinosaurs."
The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds. It examines several properties that are shared between the two species, including feathers, complex brains, the shapes. And sizes of eggs, and the ability to fly. Birds today make nests, lay eggs and tend to babies. Fossil research shows that some dinosaurs also made nests and laid eggs. Also,birds have hollow(中空的)bones, which don’t weigh much and allow birds to take more air into their lungs. These adaptations help with flight. Some dinosaurs had these properties as well. In addition, the exhibit shows that there are many similarities between the legs, claws; and feet of dinosaurs and birds.
Norell noted that the research behind this exhibit is the result of advanced scientific, techniques; and new technologies. For example researchers used a scanning (掃描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs. It combines with many X-rays to produce a 3D image. "Modern technology tells us more than we thought
we could ever know about the connections between dinosaurs and birds," Norell said.
