Possums was Anhingas (A Challenge)

Well, the comorant problem is at least moderately
well-behaved when processed w/ the standard 'Four 
Filters': predator avoidance, resource acquisition,
sexual preferance, and thermal relations. 

Now tell me why possums don't get: stronger, prettier,
faster, smarter, or anything else. (What's it been
now, =>60 mys?) 

Already taken: "Female possums just like the bottom of
the barrel", and "They've fallen so far behind they
can't catch up".
