Project description
Protocell observation in ancient rocks
The early rudimentary forms of cells that may have existed before the evolution of more complex cellular life are referred to as protocells. Funded by the European Research Council, the ProtoSigns project explores the potential observation of fossilised protocells in early rock formations. The key objective is to improve our understanding of how early protocells with simple membranes and molecular machinery have evolved to more complex forms. Researchers will employ a novel microfluidic approach to experimentally generate protocells of increasing complexity, simulating early Archean conditions. State-of-the-art techniques will characterise resulting microstructures, informing the identification of key indicators in the geological record, potentially revolutionising our understanding of life’s origin and evolution.
Objective
Fossilised remains of protocells transitioning towards the first living organisms may be observable in the early rock record distorting our interpretation of biosignatures. Protocells cellular structures existing prior to the emergence of life would have comprised simple membranes and molecular machinery. The formation of complex protocells is poorly understood. The interpretation of fossilised microorganisms in the early rock record is steeped in controversy. The potential for abiotic microstructures to further complicate this interpretation has long been recognised but has not been systematically tested. Evidence suggests that prebiotic structures are very difficult to distinguish from microfossils. However, little is known about the chemical and physical characteristics of these biomorphs that may enable us to tell the difference. This project will use a novel microfluidic approach to expand the experimental scope for formation of protocells of increasing complexity. Resulting microstructures will undergo silicification and diagenesis, the principal preservation pathway for early Archean microfossils. State-of-the-art analytical techniques will be used to characterise biomorphs, providing the first rigorous investigation of the feasibility of protocell preservation and how this might express in the geological record. These data combined with a predictive model and biological controls will allow for identification of key observables that will act as biogenicity indicators. Purported microfossils will then be examined and reinterpreted using the novel biosignatures. This project has the capacity to represent a paradigm shift in our fundamental understanding of the origin and evolution of life on Earth and possibly elsewhere in the Solar System. Collectively this will represent a major advance in our understanding of the geological record, providing the first comprehensive methodology to distinguish between abiotic, prebiotic, and biological microstructures.
