把一个苹果从它的中间切开,你就会发现里面有5个小室排列成非常对称的星放射形——一个五角星。每一个小室里都有一枚种子(偶尔也有两枚的),它是那样一种油亮的深褐色,好像一个细木匠细细地打磨过它,上了油一样。关于这些种子,有两个事实值得一提。首先,它们含有少量的氰化物,这很可能是苹果进化出来保护自己,避免动物对它们的啮咬;它们的苦涩几乎无法形容。第二,关于这些种子更重要的事实涉及它们的遗传内容,这同样也充满了惊奇。这个苹果中的每一枚种子都含有一个全新的、完全不同的苹果树的遗传结构。这样一枚种子, Cut an apple out of its middle, and you will find that there are 5 cells arranged in a very symmetrical star radial - a five-pointed star. Each chamber has a seed (occasionally two), it is a shining dark brown, as if a fine carpenter carefully polished it, the same oil. There are two facts about these seeds worth mentioning. First, they contain small amounts of cyanide, most likely the apples evolved to protect themselves from the animals’ bites; their bitterness was almost indescribable. Second, it is equally surprising that the more important facts about these seeds relate to their genetic content. Each apple in the apple contains a brand new, completely different genetic structure of the apple tree. Such a seed,
