Although mutations do occur naturally in organisms over the course of many generations, research has shown that environmental factors—radiations and chemicals—increase the rates and types of mutations. A prime example of this is the enormous increase in animal deformations in areas surrounding the Chernobyl nuclear plant. Since the accident, 197 deformed calves and about 200 abnormal piglets have been born. The severity of these deformities is frightening, including animals with no eyes, deformed skulls, and distorted mouths 中文无法翻的很顺，卡卡的 不知道如何才能自然点 虽然生物的突变在世代中会自然产生 但研究显示环境因素-核能和辐射，会导致突变的速度和种类增加 最大量的显着例子即是车诺比核电厂附近的畸形动物 自从事故发生後出生了197头畸形小牛，200头畸形小猪。 都具有严重的惊人畸形，包括没有眼睛，畸形的头颅，以及扭曲的嘴巴 请帮忙看看如何顺一点 谢谢 --
