巨型动物灭绝与去灭绝
评估关于更新世巨型动物灭绝原因的争论——是人类过度捕猎、气候变化，还是两者共同作用——并利用化石记录、古DNA和考古遗址的证据；将这一讨论与当今的第六次大灭绝联系起来，并思考利用古DNA进行去灭绝的伦理和可行性。
Evaluate the debate over what drove Pleistocene megafauna to extinction — human overkill, climate change, or a combination — using evidence from fossil records, ancient DNA, and archaeological sites; connect to the present-day sixth mass extinction and consider the ethics and feasibility of de-extinction using ancient DNA
学习证据 / Evidence
- 概述了更新世巨型动物灭绝的过度捕杀假说（人类捕猎压力）和气候假说（快速变暖），并为每种假说引用具体证据。
- 解释了如何通过对永久冻土中保存的标本进行古DNA测序，来获取灭绝物种的遗传、饮食和亲缘关系信息。
- 评估去灭绝概念——描述其所需的技术条件，并提出至少两个支持与反对的实质性科学或生态学论点。
- Summarises the overkill hypothesis (human hunting pressure) and the climate hypothesis (rapid warming) for Pleistocene megafauna extinction, citing specific evidence for each
- Explains how ancient DNA sequencing from permafrost-preserved specimens provides information about genetics, diet, and relatedness of extinct species
- Evaluates the de-extinction concept — describing what it would take technically and raising at least two substantive scientific or ecological arguments for and against

如果{{name}}听说科学家正尝试利用古DNA复活猛犸象，他们能解释什么是古DNA、存在哪些挑战，以及为什么一些科学家认为复活灭绝物种可能真的有助于生态系统吗？
If {{name}} heard that scientists are trying to bring back the woolly mammoth using ancient DNA, could they explain what ancient DNA is, what challenges exist, and why some scientists think reviving extinct species might actually help ecosystems?
