Summary

Story summary

Over 80% of Earth's biodiversity is concentrated in a few large groups that experienced rapid evolutionary radiations.
Analysis of data from over 2 million species across plants, insects, and vertebrates confirms this pattern.
Ecological opportunities and key innovations drive species diversification.
The true diversity of bacteria is largely unknown, which may impact these findings.
This research improves understanding of evolutionary processes and biodiversity distribution.
