Cooked minerals resemble life A laboratory experiment has given rise to tiny filaments that mimic structures found in ancient rocks identified as microfossils. The findings cast further doubt over whether the oldest known microfossils found in the 3.5-billion-year-old Warrawoona Group in Australia were indeed produced by living organisms, with implications for the search for early life on Earth and elsewhere.   |
