　　Dear fellow students，

　　I’m so honored to speak here on behalf of our group.

　　After a heated discussion，we agreed that the dodo is the very animal that is well worth cloning.On the one hand，compared with the aurochs，the dodo is much smaller，which means that the dodo will consume much less food①.Besides，the dodo became extinct fairly recently so its DNA is still in good condition.On the other hand，the aurochs cannot live without grasslands，while the dodo can adapt to the hot climate easily.②
