Microscopic fossils of bacterial cells that have been discovered in ancient sediments from Western Australia and South Africa, tentatively suggest that life evolved on Earth around 3.5 billion years ago, in conditions that were radically different to those found on Earth today. Until recently, extracting and subsequent processing of such delicate fossils allowed for the potential introduction of artefacts and contamination. Fortunately, within the past decade, high-resolution, nanoscale techniques have been pioneered by researchers at UWA (eg. 3D-FIB-SEM, FIB-TEM, NanoSIMS), allowing for in-situ study of these ancient life forms, and minimising contamination and secondary artefacts.
