Geography scholar discovers strong evidence for links between Africa’s drying climate and human evolution


Professor Richard Bernhart Owen of the Department of Geography has analysed African lake sedimentary cores and established connections between a drying climate and technological and evolutionary changes in early humans. He also concluded that the impact of climate change had forced ancestral humans to learn new ways of living and develop new technologies, for example, the ancestors used big and rough stone tools in the beginning and gradually developed some light, handy and more varied tools. The research has been published in Proceedings of the National Academy of Sciences of the United States of America (PNAS), one of the world’s most-cited multidisciplinary scientific journals.For more details, please refer to:

地理系歐文彬教授(Richard Bernhart Owen)分析非洲湖泊的湖芯沉積物,首次成功建立遠古的氣候乾旱化、科技及人類行為變化之間的聯繫。研究顯示古代人類受氣候轉變影響,逼使他們學習新的生活方式和技能,例如由設計及使用大型粗糙的石器,轉變為較輕巧及多用途的。該項突破性研究成果已經在國際權威跨學科期刊《美國國家科學院院刊》刊登。更多詳情,請瀏覽﹕
