RE: Mystery of Mass Extinctions Is No Longer Murky

Why oh why are papers still being written as if there could be a proven
single cause of mass extinctions.  All the excellent work on the
Permian-Triassic by Ward, Erwin and Benton shows a multitude of causes and
all the competing theories on the KT will all have played a greater or less
part in the event.

I don't remember seeing this:

The ebb and flow of the sea is the primary cause of the world's mass 
extinctions over the past 500 million years according to the national 
Science Foundation article (Press Release 08-103) based on the journal 
/Nature /report published online June 15, 2008.
