Summary
Coral-associated fish diversification is limited, with most fish lineages expanding during the Miocene, not Pliocene/Pleistocene coral diversification. Reef structure, not coral association, drove fish macroevolution.
Area of Science:
- Marine Biology
- Ecology
- Evolutionary Biology
Background:
- Tropical reef biodiversity relies on fish-coral interactions, yet their coevolutionary patterns remain underexplored.
- A comprehensive dataset reveals that only a small fraction of fish species (~5%) exhibit strong associations with live corals.
Discussion:
- Fish and coral evolutionary trajectories show a significant decoupling.
- Fish lineages expanded during the Miocene, while coral diversification peaked in the Pliocene/Pleistocene.
- Coral association did not significantly influence major differences in fish diversification rates.
Key Insights:
- The expansion of wave-resistant reef structures and associated ecological opportunities likely drove Miocene fish diversification.
- Macroevolutionary patterns in reef fishes correlate more strongly with reef expansion than with corals themselves.
Outlook:
- Further research can investigate the specific ecological opportunities presented by novel reef structures.
- Understanding macroevolutionary drivers beyond direct species interactions is crucial for reef ecosystem studies.

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

02:35What is Evolutionary History?
37.4K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

01:54Convergent Evolution
28.1K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

02:55The Evidence for Evolution
43.1K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

02:39Predator-Prey Interactions
16.5K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
