昆虫的适应
Insect Adaptations
昆虫的适应与进化：桦尺蠖是自然选择的著名例子——工业革命期间，在被煤烟熏黑的树干上，深色蛾子更容易存活。竹节虫演化出像树枝一样的外形。拟态蚂蚁的蜘蛛演化出能骗过捕食者的形态。微小的变化经过许多代积累，最终形成惊人的伪装。
Adaptation and evolution in insects: peppered moths as a famous example of natural selection (dark moths survived better on soot-covered trees during the Industrial Revolution). Stick insects evolved to look like twigs. Ant-mimicking spiders evolved to fool predators. How small changes over many generations lead to remarkable disguises.
学习证据 / Evidence
- 复述桦尺蠖的故事，并解释环境如何改变哪种颜色的蛾子最容易存活。
- 描述竹节虫的身体形态是怎样的一种适应性特征，能帮助它避免被吃掉。
- 解释适应性是通过自然选择经过许多代才形成的，而不是在一只昆虫的一生中形成的。
- Retell the peppered moth story and explain how the environment changed which colour moth survived best
- Describe how a stick insect's body shape is an adaptation that helps it avoid being eaten
- Explain that adaptations develop over many generations through natural selection, not during one insect's lifetime
