I want to know the answer to the following question:
What did Charles Darwin call the sudden appearance of nearly modern flowers in the fossil record?
All the background I'm provided with is that "However, the fossil record has considerably grown since the time of Darwin, and recently discovered angiosperm fossils such as Archaefructus, along with further discoveries of fossil gymnosperms, suggest how angiosperm characteristics may have been acquired in a series of steps.". Is that enough to answer the question?
