Massive genomic study reveals the explosive early history of flowering plants
In short: Researchers analyzing nearly 8,000 genera of flowering plants found that their early evolution was marked by rapid diversification and significant genetic complexity. By using a standardized set of 353 nuclear genes, the team was able to reconstruct a much more detailed evolutionary tree than previous studies allowed.
This large-scale genomic reconstruction provides a clearer picture of how angiosperms rose to ecological dominance. By scaling the tree with 200 fossils, the researchers observed that a huge portion of modern plant orders emerged during a period of intense evolutionary activity. However, the study's reliance on specific nuclear genes and fossil calibrations means the exact timing of these events remains an estimation.
Why it matters: A massive genomic survey shows that the ancestors of most modern flowering plants underwent a period of intense, complex evolutionary expansion.
