9. Phaenerozoic - Paleozoic - Cambrian Cambrian explosion Why did such great fundamentally different body plans evolve in such great profusion in early evolutionary history but hardly at all thereafter? How and why did so many great changes evolve in such a short period of time? rapid diversification of higher taxa
