Summary

Story summary

A study by the University of Reading finds that cacti evolve rapidly because their flowers change shape quickly.
Researchers analyzed over 750 cactus species and found that rapidly changing flowers increase speciation.
The findings challenge traditional views of plant evolution.
Nearly a third of cactus species face extinction, creating conservation implications.
The study's data appear in the Cactus Ecological Database (CactEcoDB) and were published in Biology Letters.
