Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti-herbivore defenses, selection for qualitative toxins, and acceleration of plant-herbivore coevolution. [PDF]

Am J Bot
Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.
