学习动物学要注意两大线索：一是由低等到高等进化的索，比如腔肠动物比原生动物高等体现在哪里？扁形动物腔肠动物高等体现在哪里？环节动物又比扁形动物高等在里？等等。另一线索是结构和功能的适应及与生活环境的应，比如猪肉绦虫怎样适应寄生生活的？蛔虫怎样适应寄生活的?
Learning zoology should pay attention to two major clues: First, the evolution from low to high, such as coelenterates higher than the protozoan where? Where is the high level of coelenterates in flat animals? Is the annelid higher than the flat animal? and many more. Another clue is the adaptation of the structure and function and the response to the living environment. For example, how does a pork locust adapt to parasitic life? How do locusts adapt to life?
