echidnas的意思|echidnas的解释-里氏词典

n. [脊椎] 针鼹（echidna的复数）

The theory seems plausible for platypuses, which are amphibious creatures. Echidnas, however, dwell solely on land.
这个理论对两栖的鸭嘴兽来说有些道理，然而针鼹却是完全陆生的动物。
Phillips and his colleagues suggest that platypuses and echidnas made it through the marsupial invasion because their ancestors sought refuge where marsupials could not follow—the water.
菲力普斯和同事认为，鸭嘴兽和针鼹能熬过有袋类动物的大军压境，是因为牠们的祖先避居到有袋类无法跟进的地方：水里。
But Phillips's team reanalyzed 439 features of those early fossils and found that echidnas and recently evolved platypuses were better grouped together instead of with more ancient fossils.
但菲力普斯的团队在重新分析那些早期化石的439个特徵后，发现针鼹和新近演化出来的鸭嘴兽较为接近，而不该和较远古的化石归类在一起。
