Day 59:

Prosanta Chakrabarty: Four billion years of evolution in six minutes

六分钟了解四十亿年的地球进化史 | TED演讲_腾讯视频

按照设定的pattern，今天主要关注三个维度中的第二个维度，演讲方式，我以面和体的形式记录下自己的理解。

面（段） 

颠覆常识（吸引注意力）

我们学习的自然科学告诉了我们猴子如何进化成为人的，而这也成为了‘常识’，讲者开头颠覆常识的问题和答案引发一部分听众好奇心，或许也同时激起另一部分听众本能的防卫／反驳的心理，但不管是哪种，都能成功吸引听众注意力。

- If we evolved from monkeys, why are there still monkeys? Well, because we're not monkeys, we're fish.

Why/What/How 论证观点

讲者在阐述自己观点的过程中，不断的以Why/What/How的形式来叙述。

- Why we are fish? why it matters? etc.

- We are also not the goal of evolution. The first animal to develop a backbone are fishes. They are all the product of that.. etc.

-...so you see, we didn't evolve from monkeys, but we do share a common ancestor with them.

体（章）

这篇演讲的目的是传递信息：进化论中‘where we came from'研究的不同视角—We are fish. 整篇演讲以提出新的观点——阐述理由——总结留白(后续研究）

开篇提出颠覆常识的问题并给出出人意料的答案，吸引听众注意力。

- If we evolved from monkeys, why are there still monkeys? Well, because we're not monkeys, we're fish.

阐述自己对进化论的理解

- ...but life doesn't evolve in a line..

演绎推理‘We're fish'

-... so technically, you and I are fish

总结（呼应开头自己提出的结论）并且有留白

- Perhaps it's better still to think of us as a little fish out of water.

- ... that still has a lot of learning to do about who we are and where we came from.
