灭绝与快速变化
Extinction & Rapid Change
解释环境变化如何可能超过物种通过自然选择适应变化的速度，从而导致灭绝，并使用历史和当代的例子说明。
Explain how environmental change can outpace a species' ability to adapt through natural selection, leading to extinction, using historical and contemporary examples
学习证据 / Evidence
- 解释为什么当环境变化快于物种适应速度时会发生灭绝
- 举出一个历史实例（如猛犸象、渡渡鸟）和一个当代濒临灭绝的实例
- 区分背景灭绝速率与大规模灭绝
- 解释人类活动（栖息地丧失、捕猎、气候变化）如何导致当前物种丧失
- Explains why extinction occurs when environmental change is faster than the rate of adaptation
- Gives a historical example (e.g. woolly mammoth, dodo) and a contemporary example of threatened extinction
- Distinguishes between background extinction rates and mass extinctions
- Explains how human activity (habitat loss, hunting, climate change) is driving current species loss
评估问题 / Assessment
如果{{name}}被问到为什么猛犸象已经灭绝而其他大型哺乳动物却存活下来，他们能否解释导致猛犸象灭绝的条件，并将其与当今濒危物种面临的情况联系起来？
If {{name}} was asked why woolly mammoths no longer exist while other large mammals survived, could they explain what conditions led to the mammoth's extinction — and connect it to what's happening with endangered species today?
