So what we're going to actually do is

实际上我们主要要研究的
we're going to look at a highly simplified model of evolution,

是一个高度简化的进化学模型
at least for today.

最少今天是这样的
We might get onto a more complicated model on Monday,

下周一我们会学到更复杂一点的模型
but today it's going to be very highly stylized.

不过今天的却是非常程式化的
So this is going to be our extremely simplified model.

也就是说今天讲的是个及其简化的模型
This simplified model is going to do tremendous violence to the biology,

这个模型在生物学领域绝对上不了台面
but it's really just to fix some ideas.

但是它却能说明些问题
So we're gonna focus on what we're gonna call within species competition.

我们主要专注于种内竞争
So the lions are competing against the lions

即狮子与狮子竞争
and the ants are competing against the ants.

蚂蚁与蚂蚁竞争
The way we're going to think about this is

我们如何研究呢
