Effect Of A Giant Meteorite Impact On Paleoarchean Surface Environments And Life
Large meteorite impacts must have strongly affected the habitability of the early Earth. Rocks of the Archean Eon record at least 16 major impact events, involving bolides larger than 10 […]

Unveiling Ancient Life: New Method Sheds Light On Early Cellular And Metabolic Evolution
Fossils don’t always come in large, dinosaur-sized packages. Microfossils refer to a type of fossil that is so small, it can only be perceived with a microscope. These microfossils can […]
