[FROM ROCKS TO GENES AND BACK:
 STORIES ABOUT THE EVOLUTION OF  PHOTOSYNTHESIS]

In part two of this 9-part series, Dianne Newman explores the deep
connection between bacteria and rocks Ñ specifically, the possibility
that some varieties of ancient microorganisms gave rise over millennia
to vast mineral deposits.

SPEAKER:
Dianne K. Newman
Professor of Geobiology, Division of Geological and Planetary Sciences
and Division of Biology, California Institute of Technology
Investigator, Howard Hughes Medical Institute

[QUOTE]
"When did the transition occur from an anaerobic world to aerobic world,
as catalyzed by biological processes that produced oxygen.... The
geochemical evidence is persuasive: around 2.4 billion years ago, we did
transition into a world with an ozone layer, with appreciable oxygen in
the atmosphere. But the intervening period is ambiguous, to say the
least."
-- Dianne K. Newman
