In their recently in communications biology published study Zhen Guo and Wolfgang Kiessling shed light on regional diversity patterns. The essence of the study is as follows.
🔬 Regional vs. Global Diversification: What do the fossils really say?
– 76% of plate-level turnover comes from immigration & local extirpation, not pure speciation/extinction.
– Regional diversity signals are strongly skewed by local sampling, preservation, and geology.
Bottom line: Global analyses are still vital for uncovering true macroevolutionary patterns over deep time.
