Medea hypothesis (Planetary science 🪐)

The Medea hypothesis is a term coined by paleontologist Peter Ward for a hypothesis that contests the Gaian hypothesis and proposes that multicellular life, understood as a superorganism, may be self-destructive or suicidal. The metaphor refers to the mythological Medea, who kills her own children. In this view, microbial...

Extinction event (Evolutionary biology 🧬)

An extinction event is a widespread and rapid decrease in the biodiversity on Earth. Such an event is identified by a sharp fall in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the background extinction r...

Huronian glaciation (Glaciology 🗻)

The Huronian glaciation was a period where at least 3 ice ages occurred during the deposition of Huronian Supergroup. Deposition of this largely sedimentary succession extended from approximately 2.5 to 2.2 billion years ago, during the Siderian and Rhyacian periods of the Paleoproterozoic era. Evid...

Verneshot (Volcanology 🌋)

A verneshot is a hypothetical volcanic eruption event caused by the buildup of gas deep underneath a craton. Such an event may be forceful enough to launch an extreme amount of material from the crust and mantle into a sub-orbital trajectory, leading to significant further damage after the material crashes back down to the surface.
