#529. 青铜时代的演化风暴:古DNA揭示人类演化的隐秘拐点——哈佛教授David Reich深度访谈

David Reich's team found that the Bronze Age (around 4,000–5,000 years ago) was humanity’s most intense evolutionary turning point—stronger than the shift to agriculture—based on analysis of over 20,000 ancient genomes.

入选理由:青铜时代自然选择强度超越农业革命,基因频率在4000-5000年前剧烈偏移
