“Continents are sort of like icebergs,” says study author Keith Klepeis, a structural geologist at the University of Vermont. “What you see at the surface is not really the full extent of the beast.”

The discovery, described in the journal Geology, may help solve a riddle that’s long perplexed scientists. Most continents contain a core of rock known as a craton, a sort of geologic nucleus at least a billion years old that acts like a stable base upon which continents build. Until now, though, the oldest continental crust found on Zealandia was dated to roughly 500 million years ago—relatively youthful in geologic terms. So if Zealandia is a continent, why did its craton seem to be missing?

This newfound fragment of ancient rock may be part of the missing piece for Zealandia. The discovery “ticks the final box,” Turnbull says. “We are sitting on a continent.”

Gain-of-function experiments aim to increase the transmissibility and virulence of existing viruses, making them deadlier for humans. The stated purpose is to better understand pathogens and to develop vaccines for possible future pandemics. Critics say this type of research is extremely dangerous and should be banned or regulated. They claim it has not prevented any pandemics to date, and that the COVID-19 outbreak might be the result of an accidental release from a lab that was conducting gain-of-function research.
