👉 Palaeobiogeography is a field of study that examines how ecosystems have changed over time, often through changes in temperature, climate, land use, and human activities. This field involves studying ancient records and fossils to understand how species have evolved from their current forms and the impacts of those changes on biodiversity. Palaeobiogeography has been used to help scientists better understand the evolutionary history of life on Earth and to predict future changes in ecosystems.
