| Chinsamy’s work raises a question central to the debate over dinosaur physiology: did dinosaurs form fibro-lamellar bone because of an innately high metabolic rate associated with warm-bloodedness or because of periods of unusually fast growth that occurred under favorable environmental conditions? (Although modern reptiles generally do not form fibro-lamellar bone, juvenile crocodilesraised under optimal environmental conditions do.) This question remains unanswered;indeed, taking all the evidence into account, one cannot make a definitive statement about dinosaur physiology on the basis of dinosaur bone.
 我怎么觉得Q33可以从黄色高亮部分得出E啊? 
 还有35 不选的E是不是因为红色高亮部分 |
