Phosphorus identified as the missing link in evolution of animals
Date:10/28/2010

A University of Alberta geomicrobiologist and his PhD student are part of a research team that has identified phosphorus as the mystery ingredient that pushed oxygen levels in the oceans high enough to establish the first animals on Earth 750 million years ago.

By examining ancient-ocean sediments, Kurt Konhauser, student Stefan Lalonde and other colleagues discovered that as the last glacier to encircle Earth receded, leaving behind glacial debris containing phosphorus that washed into the oceans. Phosphorus is an essential nutrient that promoted the growth of cyanobacteria, or blue-green-algae, and its metabolic byproduct is oxygen. The new, higher oxygen levels in the ocean reached a threshold favourable for animals to evolve.

Konhauser's past research into ancient phosphorus levels in a unique suite of rocks called banded iron formations led him and his colleagues at the University of California Riverside to their current findings.

In 2007, Konhauser and his U of A team published research in the magazine Science that was contrary to the then-accepted theory that phosphorus was scarce throughout much of Earth's history, it was in fact plentiful.

"Now in 2010 we showed that phosphorus levels actually peaked between 750 and 635 million years ago at the very same time that oxygen levels increased, allowing complex life forms to emerge," says Lalonde. "That establishes our link between phosphorus and the evolution of animals."
