One scenario is that an AI ends up designing the study, writing the code, plotting the results and writing up the ms. And another AI, possibly a different one, does the peer-review and decides on the quality.

Geophysical and geological evidence indicate that the Mediterranean became isolated from the ocean ~5 million years ago due to the tearing of a lithospheric slab under S Spain. The dry Mediterranean climate then caused the accumulation of a km-thick layer of salt, today buried under sediment. 1/3
