> > 
> > DAVID: [i]Very educational study of whale size limits. They can evolve to a dangerous size for their continuing existence. My bold is a major point. Top predators control ecosystems unless or until they eat themselves out of a job, or prey disappear. The bush of life requires active econiches/systems.[/i]
> > 
> > dhw:  Of course it does. Every single organism that has ever lived depends or depended on econiches that provide food. Could anyone possibly disagree? (NB this subject has nothing whatsoever to do with the theory that a God personally designed every econiche for the sole purpose of keeping life going until he fulfilled his one and only purpose of designing H. sapiens. Thank you for keeping the two subjects separate.)
