Impact craters may have been cradles of life
The University of Western Australia said:
Even comparatively small meteorite impact craters may have played a key role in the origin and evolution of early life on Earth, according to a researcher at The University of Western Australia.
Geologist Martin Schmieder, a research associate in UWA's School of Earth and Environment, said study results suggested that heat generated by an asteroid impact took at least several hundred thousand years to dissipate.
Dr Schmieder, the lead author of an article published this month in the prestigious journal Geochimica et Cosmochimica Acta, said as impact craters cooled, they provided an ideal environment for microbial life to thrive
