Study finds angiosperm reproductive diversification predated the end-Cretaceous extinction
By
Cindy V. Looy
Summary
This article presents a scientific study on angiosperm (flowering plant) reproductive evolution, challenging the traditional view that links it primarily to the end-Cretaceous extinction event. The researchers report diverse and unexpectedly large diaspores (seed dispersal units) that predate the Cretaceous-Paleogene boundary, suggesting that diversification of reproductive strategies in angiosperms occurred before the mass extinction, not as a direct consequence of it. The study provides fossil evidence that reshapes understanding of plant evolutionary history.
