Description | To date, highlights of our in-progress research project include: 1) The discovery that the fossil record of fishes is not as strongly biased by aspects of the geological record as is the fossil record of land-living backboned creatures. This has important implications for estimating past species diversity and assessing the relative impacts of major extinction events, both of which provide important historical context for current biological crises. 2) The discovery, based on the fossil record of Great Britain, that the diversity of fishes has increased toward the modern day, and that this increase does not appear to be a consequence of a biased palaeontological record. 3) The discovery that, when combined, fossil and molecular-genetic resources provide a well-supported picture for the evolutionary origin of biological diversity in ray-finned fishes, which include roughly half of all living vertebrate species, and are of considerable economic and scientific importance. 4) The discovery that aspects of evolution in a particularly diverse group of ray-finned fishes, known as spiny-rayed fishes, show patterns characteristic of 'adaptive radiations'. These patterns are best known for species on short timescales in restricted geographical areas, so our analyses of a widespread and geologically long-lived group provide an important complement to these studies. 5) The discovery that the spectacularly diverse fishes living on coral reefs entered that important habitat in two 'bursts': one before and one after the extinction 66 million years ago that killed the dinosaurs. 6) The discovery that the specialized jaw structure of spiny-rayed fishes, which allows them to feed on elusive prey, evolved over 100 million years ago, and that species showing this capability have increased in frequency in the time that has followed. |
Exploitation Route | By targeting the evolutionary histories of a well-known and charismatic group of organisms, the outcomes of this research can be used as a tool to help foster public awareness of key topics related to the origin and maintenance of biodiversity over very long (geological) timescales. Our results form necessary context for future work that seeks to examine the origin of half of all vertebrate species alive today. This represents critical historical and evolutionary background for the diversity of research that uses fish model systems. We anticipate that new statistical methods for estimating the timing of evolutionary events currently under development as a component of this work will represent a major new contribution to the study of the co-evolution of life and the planet. |
