Revisiting the oldest evidence for life on Earth

This travel grant supports fieldwork at Isua, Greenland. The aim of the trip is to collect samples across the locality that hosts the oldest (>3.7 Ga) proposed evidence for life on Earth. A detailed investigation of the new samples, using geochemistry and thermodynamic modelling, will test the hypothesis that the organic matter at this site is far younger (~2.6 Ga) than previously assumed.
