I am afraid that what this thread demonstrates is: there are few fields
of science more littered with the debris of re-invented wheels than
coral reef biology.

Turns out there have been DOZENS of these exercises, since Rose and
Risk 1985. None of them built on what went before, they all started

Just think how much further ahead we would be if we even stood on the
shoulders of pygmies...or read more.
