Life may have triggered plate tectonics.

what the fuck, that's wild. also first time I've seen an article include one of these ( how plain the Language is is up for debate)

Plain Language Summary

Plate tectonics provides a basic framework for understanding geological processes on Earth. Although the subduction of cold and heavy oceanic lithosphere can maintain the operation of plate tectonics, its initiation mechanism remains unclear. To reveal the origin mystery of plate tectonics, it is necessary to clarify how and when the first subduction on Earth began. In this study, we propose a hypothetical model that links Earth's biological processes with the origin of plate tectonics. In the photic zone of the Neoarchean continental margins, the anaerobic metabolism of photoferrotrophic bacteria greatly promoted the massive deposition of magnetite-rich banded iron formations (BIFs). Our mechanical calculations show that within an acceptable sedimentary thickness, these heavy BIF deposits can provide enough downward force to rupture the Neoarchean continental margins and initiate the earliest subduction. The peak deposition of BIFs in 2.75–2.4 Ga further implies the onset time of global plate tectonics.
