Finding a double yolk at breakfast is considered lucky - but one pensioner was amazed when he cracked open an egg only to find a complete miniature one inside. 就算是“双黄蛋”对你已经不足为奇，但这样的“蛋中蛋”肯定会让你倍感惊奇。 Retired farmer John Fellows, 68, had been making scrambled eggs when he cracked open the large outer shell of the ordinary chicken egg.But when he put it aside to clean up, he spotted the a smaller egg the size of a marble inside. 68岁的约翰-菲罗斯是英国的一位退休农民，这天清晨他准备煎蛋做早餐，但当他敲开一枚体积要比普通鸡蛋更大鸡蛋后，他惊讶的发现，蛋壳内居然还有一枚小鸡蛋。

It's one of those things that can happen.
“一枚鸡蛋在母鸡的体内十分的靠近另一枚正在形成的鸡蛋，最总这枚鸡蛋被‘包裹’进了另一枚蛋中，这样的情况是可能发生的。”
Douglas Russell, of the Natural History Museum, said the 'ovum in ovo' has attracted scholarly attention for hundreds of years. He said: 'Several theories have been proposed.'The most likely suggests that the normal rhythmic muscular action, or peristalsis, that moves a developing egg down the oviduct malfunctions in some way.'
来自英国自然历史博物馆的道格拉斯·拉塞尔说，“蛋中蛋”的现象在长久以来都吸引着学者的关注，他们也提出了很多理论。最为接近的一种理论认为，这是由于将鸡蛋排出输卵管的正常肌肉运动出现功能异常所造成的。 |
