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: https://cpro.hkbu.edu.hk/en/press_release/detail/HKBU-Geography-scholar-discovers-strong-evidence-for-links-between-Africas-drying-climate-and-human-evolution/
