Researchers from University College London (UCL) have discovered fossil evidence for the earliest life forms yet found on Earth. Microscopic filaments of primitive bacteria recovered from a sequence of iron-rich sedimentary and volcanic deposits located in northern Quebec, Canada which push back the record of life on Earth to some 4.2 billion years ago, some 400 million years earlier than the previous record.
Dr Alex Mitlehner, Geoscience course director at Greene’s Tutorial College, Oxford and former researcher at UCL with a publications record in the field of microfossils, considers this a milestone in scientific discovery said,
“This find pushes back evidence for life on Earth and leaves the possibility open for discovering fossil evidence for similar life-forms, here and elsewhere in the Solar System, including Mars and the moons of Jupiter and Saturn. Students studying the new Greene’s Geoscience diploma will be able to learn about this and similar discoveries, and who knows may themselves one day be at the forefront of similar breakthrough scientific research”.
