What about life? The empirical evidence for the origin of life
is in flux. Earlier dates
were supported by isotope fractiona-
tion data and fossils that are now disputed; what was once
interpreted as an early sign of life may in fact be due to sim-
pler chemistry and physics. It now seems that the most ancient,
minimally controbversial sign of life on Earth is deposit of

carbon atoms. Carbon has heavier (13C) and lighter (12C) stable isotopic atoms, and this old carbon, dated to 3.85 Gya, has
the carbon-isotope ratios (enriched in 12C) characteristic of
biochemistry.
