EurekAlert [USA], 4-Oct-2010
Biodiversity decreases towards the poles almost everywhere in the world,
except along the South American Pacific coast. Investigating fossil
clams and snails Steffen Kiel and Sven Nielsen at the
Christian-Albrechts-Universität zu Kiel (CAU) could show that this
unusual pattern originated at the end of the last ice age, 20.000 to
100.000 years ago. The retreating glaciers created a mosaic landscape of
countless islands, bays and fiords in which new species developed
rapidly – geologically speaking. The ancestors of the species survived
the ice age in the warmer Chilean north.
