Looking at the Earth's productivity through
ancient history provides a glimpse into how life is
likely to behave over its entire existence -- in
addition to informing observations of atmospheres
on planets outside our solar system.
"The size of the biosphere through geologic time
has always been one of our biggest questions in
studying the history of the Earth," said Erik
Sperling, an assistant professor of geological
sciences at Stanford who was not involved with
the study. "This new proxy demonstrates how
interlinked the biosphere and levels of oxygen and
carbon dioxide in the atmosphere are."
