We use 'Big Data' approaches, evolutionary trees and detailed study of fossils to determine how global events, environmental change and ecological interactions shaped long-term change (macroevolution) and established modern biodiversity.
Deep-time databases for early vertebrates (half of vertebrate history), ray-finned fishes (half of vertebrate diversity), marine ecosystems and mass extinctions provide our test cases.
