Also there have been eras in earths history where it was basically like one of two environments. Like before the continents emerged from the oceans properly, or the several snowball earths, or the multiple times a super continent formed and created swamp land and desert land because of the fucken Appalachian mountains.
Probably helps that grasses evolved since the dinosaurs got Cained by the universe. Honestly the variation seen in the Holocene is probably the direct result of the Yucatan impact and the Great Dieing before it.

Yeah, the holocene is a weirdly varied time period for climates. Grasslands and similar ecosystems are pretty new geologically.
