Paul Hoffman is the 2024 Kyoto Prize Laureate in Basic Sciences. He is an adjunct professor at the University of Victoria, has conducted groundbreaking research in the "Snowball Earth" (global freezing) hypothesis and plate tectonics occurring in the first half of the Earth's 4.6-billion-year history. After earning his doctorate from Johns Hopkins University, Hoffman served the Geological Survey of his native Canada for 24 years followed by teaching at Harvard University and conducting related research in Sub-Saharan Africa. He has geologically demonstrated the occurrence of the postulated global freeze, so-called "Snowball Earth," which drove the rapid diversification of animals in the Cambrian period approximately 520 million years ago.
