Hydrothermal systems, early life on Earth and implications for astrobiology
Astrobiology seeks to answer questions regarding the origins and extent of life in the Universe. Geology provides a window in time that offers evidence needed to address these astrobiological questions. The study of ~3.5 billion years old stromatolites from the Pilbara, Western Australia has shown that some of the earliest evidence of life on Earth was thriving in hot springs on land. This evidence provides a geological perspective that may be relevant in origin of life studies, and subsequently for implications in the search for life elsewhere.
