moral behavior patterns

I think when one starts observing everyday behavior one can start seeing patterns where doing something good will actually later result in less effort in continuing some kind of moral behavior.

我想，一个人在观察每日行为时，就能看出做积极的事实际上会导致人们在做符合道德的行为方面不那么努力。

Instead, drawing upon observations of his children, animals at the London zoo, and his faithful dogs, Darwin showed how our moral sentiments are expressed in mammalian patterns of behavior.

相反，从对他自己的孩子、伦敦动物园的动物以及他忠诚的家犬的观察当中，达尔文表明，我们的道德情感是以哺乳动物的行为模式来表达的。
