| 形形色色 | xíngxíngsèsè | all kinds of; a variety of | |
| 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

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 比如kūyèdié 枯叶蝶gùmíngsīyì 顾名思义tā 它de 的yánsè 颜色hé 和xíngzhuàng 形状jiù 就xiàng 像yī 一piàn 片kūyè 枯叶yīyàng 一样suǒyǐ 所以dāng 当tā 它tíng 停zài 在shùzhī 树枝shàng 上shí 时zhàkànzhīxià 乍看之下jiù 就gēn 跟pǔtōng 普通de 的yèzi 叶子yīyàng 一样
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

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 枯叶蝶wěizhuāng 伪装chéng 成yèzi 叶子biànsèlóng 变色龙gǎibiàn 改变zìjǐ 自己de 的yánsè 颜色dōu 都shì 是wèile 为了duǒbì 躲避tiāndí 天敌bǎohù 保护zìjǐ 自己
Orange Oakleaves mask as leaves and chameleons change their skin color in order to avoid predators and to protect themselves.
