自然选择 zìránxuǎnzé natural selection
动物在不同的自然环境中，为了生存它们会慢慢透过繁殖、变异而演化出形形色色功能不同的颜色，而这些颜色是由自然选择决定的。
dòngwù zài bùtóng de zìrán huánjìng zhōng ，wèile shēngcún tāmen huì mànmàn tòuguò fánzhí 、biànyì ér yǎnhuà chū xíngxíngsèsè gōngnéng bùtóng de yánsè ，ér zhèxiē yánsè shì yóu zìránxuǎnzé juédìng de 。
Animals living in different natural environments will mutate and evolve into having a variety of functions and different colors for their survival. These mutations are based on natural selection.
比如枯叶蝶顾名思义，它的颜色和形状就像一片枯叶一样，所以当它停在树枝上时，乍看之下就跟普通的叶子一样。
bǐrú kūyèdié gùmíngsīyì ，tā de yánsè hé xíngzhuàng jiù xiàng yī piàn kūyè yīyàng ，suǒyǐ dāng tā tíng zài shùzhī shàng shí ，zhàkànzhīxià jiù gēn pǔtōng de yèzi yīyàng 。
For example, the Orange Oakleaf, as evident from its name, has wings that are of the colors of a dead leaf. So when it lands on a branch, it looks exactly like a normal leaf at a glance.
再比如变色龙，它是蜥蜴的一种，“蜥”如其名，它会随着周遭的环境改变自身的颜色。
zài bǐrú biànsèlóng ，tā shì xīyì de yīzhǒng ，“xī ”rú qí míng ，tā huì suízhe zhōuzāo de huánjìng gǎibiàn zìshēn de yánsè 。
Another example could be the chameleon. It is a type of lizard. Just as its name, it will change its skin color based on its surrounding environment.
枯叶蝶伪装成叶子、变色龙改变自己的颜色都是为了躲避天敌、保护自己。
kūyèdié wěizhuāng chéng yèzi 、biànsèlóng gǎibiàn zìjǐ de yánsè dōu shì wèile duǒbì tiāndí 、bǎohù zìjǐ 。
Orange Oakleaves mask as leaves and chameleons change their skin color in order to avoid predators and to protect themselves.
