小马分类上---------生物学—第五篇（animal behavior）
错误的，意识中不记得的，没有听清楚的，去掉的
听写：(画线部分主要框架)

For them a beautiful face and body are reasonably reliable indicators of underline quality and experiments had shown that many species appear to look for at least one classic characteristic of beauty: mainly semitry(symmetry对称性).

selective part(partner) in a pair usually the female seek the maximum possible balance between the left and right half of a potential mate’s body. For example, certain female birds first attract(check) to see if the male's left wing is as(the) same length and shape as(of) the right to get clues about the bird’s health and strank(strength). Now, what other evidences do we have of this kind of behavior? Well, in one experiment, researchers put color bands on the legs of male finches. The female by far prefers males with same color on both legs over those that had a different color on each leg. Another experiment, involving male ox(elks麋鹿) indicate the importance of symmetry in the aclers(antlers鹿角). 8th sematical labs(Asymmetric 不对称的antlers) of course, indicate that the male has lost afight to another male and he is therefore, not the strongest。

听写前听了两遍：
主要讲动物beautiful的作用。
人们常说人不可貌相，但是researchers们说动物的beautiful可能和这个理论相违背。动物的美丽是不记得说什么了，反正是有意义的
提到了一个理论：mainly s
在这个理论中，有两个evidence
第一个：female birds attract male birds, balance the health body, shape.
第二个: 用color，coak 。
猜测：coak 对它们认为beautiful的颜色就比较有斗志。
论据框架有问题，三个方面：1、翅膀长度和形状；2、颜色的平衡，3、鹿角的完整
笔记
人们常说人不可貌相，但是researchers发现动物的相互吸引行为可能和这句谚语相反，可能是underline quality. 讲到一个理论。这是一种可靠的判别对方能力的方法，今天主要讲一个经典的品质：主要的对称性。（出错原因：对称性symmetry不认识）
Predict----------为什么？解释
雌性动物喜欢雄性动物的形体的左右对称，比如雌鸟喜欢雄鸟的左右翅膀长度和形状是一致的。
Predict---------怎么证明
科学家给公鸡的腿上系上带有颜色的带子，母鸡喜欢两条腿上带子颜色一样的公鸡，而不喜欢一腿一色的公鸡
还有一个试验是有关公牛的，怎么操作没听懂，反正就是有一个在角斗中失败了，这就证明了它不是最强状的。猜测：可能是腿形不一样？？？
麋鹿角：如果麋鹿的角是不完好的，证明在某次角斗中失败了，从而证明他不是足够的强壮有力。（错误原因：麋鹿，角不认识）
