Caption
Emergence of new species of the coccolithophere (calcite producing marine algae), paced by approximately 400,000 year variations in the shape of Earth’s revolutions around the sun (eccentricity shown in inset) has been documented by the changes in the shape and size of their internal calcite plates shown here in photos obtained from scanning electron microscope.
