Here we examine the global movement of Labyrinthulomycetes protist strains that current results indicate evolved during the Neoproterozoic snowball Earth. Our findings show the presence of a genetic variation, at an rRNA gene locus, along a thermal axis that is independent of the protists' global positions and that tropical strains were sampled on a subarctic hydrothermal vent. Assuming a global ubiquity of microbes, thermal adaptation could indicate that the protists have already adapted to the impact of climate warming. In this context, vent communities could conceivably help predict the impact of climate change on the ecology and niche retention of organisms across the warming world.
