• 
  
  and Game Theory that we've been doing so far in the class.
  和我们之前讲过的博弈论有很大区别
• 
  
  And that is, that we're going to think of behaviors,
  最主要的区别就是要把动物的行为
• 
  
  these strategies played by animals,
  即动物们采取的策略
• 
  
  not as chosen by reasoning individuals but rather as being hardwired.
  看成是天生的 而不是自由选择的
• 
  
  So if strategies grow
  如果持某种基因的狮子或蚂蚁数量壮大了
• 
  
  it isn't that lion or ant has chosen that strategy.
  这并不是说它们就选择了这种策略
• 
  
  It's simply that the ant or lion who has that gene
  这仅能说明带有该基因的狮子或蚂蚁
• 
  
  that corresponds to that strategy grows and has many children.
  能繁衍出很多的后代来而已
• 
  
  So it's important, this is a new idea for us,
  这一点很重要 它是个全新的概念
• 
  
  that these strategies are hardwired.
  策略是天生的
• 
  
  So it's interesting, in and of itself,
  这一点很有意思
• 
  
  but there's also an important influence the other way.
  但是还有另一个重要的原因
