Red pandas are native to the high forests of Asia. They are only a little bigger than a house cat and considered to be endangered. Scientists reported last month that not all red pandas belong to the same species. There are two different species of this animal，not just one，a study found. The scientists reported finding major differences in three genetic markers between Chinese red pandas and Himalayan red pandas. Scientists identified the markers after studying DNA from 65 of the creatures. DNA carries genetic information for the development，growth and reproduction of living things. Documenting the existence of two separate species could help guide efforts for protecting red pandas，scientists added.

Chinese red pandas live in northern Myanmar，as well as southeastern Tibet，Sichuan and Yunnan provinces in China. Himalayan red pandas are native to Nepal，India，Bhutan and southern Tibet in China，the researchers said.

Conservation biologists Yibo Hu and Fuwen Wei 1ed the study.　 “To conserve the genetic uniqueness of the two species，we should avoid their interbreeding(杂交繁殖)in captivity，”Hu said. “Interbreeding between species may harm the genetic adaptations already established for their local habitat environment. ”

Scientists had earlier suggested there were two species of red panda. But the new study was the first to provide the genetic information necessary to permit such a judgment. International experts estimate a total population of around 10，000 red pandas in the wild. The two species differ in coloration and skull shape. The Himalayan red panda is the rarer of the two.

Major dangers to red pandas include deforestation and habitat loss. While they have similar names，red pandas and giant pandas are not closely related. Giant pandas are one of the world’s eight bear species. Red pandas are sometimes called living fossils because they have no close living relatives. They are the only remaining member of their mammalian family.

1.What is the purpose of recording the existence of the two different species of red panda?

A.To direct efforts for the protection of them.

B.To better distinguish red pandas and giant pandas.

C.To inform people there exist two species of red panda.

D.To confirm there are major differences between them.

2.In which place can we spot Himalayan red pandas?

A.Southeastern Tibet. B.Yunnan Province.

C.Southern Tibet. D.Northern Myanmar.

3.What can we know about the two species of red panda?

A.They belong to the same animal family as giant pandas.

B.Their existence has been known already.

C.They differ mainly in size and shape of skull.

D.To protect them，we should interbreed them.

4.In which section of a newspaper may this text appear?

A.Lifestyle. B.Culture.

C.Entertainment. D.Science.
