Cacti are evolving shockingly fast and scientists just learned why
Latest Science News -- ScienceDaily·May 13, 2026
Cacti may look like slow, stubborn desert survivors, but they’re actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn’t flower size or specialized pollinators, but how quickly cactus flowers change shape over time. The finding overturns a long-standing idea dating back to Darwin and reveals deserts as surprisingly dynamic ecosystems where evolution is happening fast.
