Gender and Genesis in Biographic Sex Part 4
In the beginning, and for hundreds of millions of years, the earth’s seas were seething with multiplying molecules. There was no sex and nothing much changed for eons, until one day some simple cells exchanged genes, and changed the world — literally. Those simple cells that had sex, evolved.
在最初的几亿年中，地球上的海洋里活跃着不断繁殖的分子。没有性，而且这种情形在很长时间没有多大改变。直到有一天，一些简单的细胞交换了基因，从而改变了世界。那些简单的有性细胞进化形成。

Hostess It began with the first species that covered the globe.
从遍及全球的第一个物种开始。

Warren H. Wagner, Jr.M3（青年男）： Plants are basic. They’re the food for all the world. And I consider biology the study of plants and their parasites. And everything else is a parasite on plants. They eat them. We do. And if we don’t eat the plants, we eat something that ate the plants.
植物是基本的。它们是世界上所有动物的食物。我认为生物
学就是研究植物及其食客的科学。其他生物都以植物为食。
它们吃植物。我们也吃。如果我们不吃植物，我们就吃那些
吃植物的东西。

Hostess A botanist like Professor Warren Wagner can be forgiven for being a plant chauvinist. After all, in the beginning came pond scum.
植物学家沃伦·瓦格纳认为植物至上，这情有可原。毕竟，最先出现的生物是绿藻。

Warren H. Wagner, Jr.M3（青年男）： It starts with a green algae 0829and, the, the green algae have all sorts of life cycles. Then they, you get to the ferns, and the ferns have the simplest life cycle of all. They’re quite decent. But then when you get to the sea plants, and particularly the flowering plants, it’s really complicated, and you get many, many, many different forms of sexual reproduction.
最初是一种绿藻。（0829）绿藻具有各种各样的生命周期。然后是蕨类植物，蕨类植物的生命周期是最简单的。但是到了海洋植物，特别是开花植物的时候，情形非常复杂，出现了许多，许多，许多种不同的有性生殖形式。

Hostess But what’s the point? Why is there plant sex?
但是为什么？为什么植物有性？
0853-0925
Warren H. Wagner, Jr.M3（青年男）： The pr…present thinking, I think, is that sex is necessary for
the evolution of plants. Plants require few specialties. One of them is to reproduce, to reproduce themselves, to occupy space. And the other one is to change. You’ve gotta change, because there’s changes in climate, changes in rainfall, changes because of new kinds of organisms, and in order to be in this melange of all these constantly changing things, you’re gonna have to change yourself, and the only way to do that is through sex.
我认为，植物的进化需要性。植物需要一些特性。其中之一就是繁殖，繁殖自身，占领空间。另一个是改变。必须改变。因为气候在改变，降雨量在改变，物种在改变，要想在这些不断的变化中幸存，你就必须改变自己，而唯一的办法是通过性。

Hostess But plants have roots. They can’t move around much, so for there to be sex in the flowerbed, plants have to find a go-between to exchange their genes.
但是植物有根。它们不能到处移动，所以要想在原地繁殖，植物必须找到一种媒介来交换基因。
