well,
"one fell swoop" might mean historically-
some of the first discussion of Newton as to if a rock fell in China and West isnt Newton still correct..to any number of these metaphors recently.
&
"species appear fully clothed" might express a former DARWINIST cover-up that Aggasiz noticed but reformed with sophisticated philosophy of chance removing by incidence (which needed to have been congruence)the lack that THEY ARE NOT FULLY FORMED (obviously)!
A record is not a fact. SOOO a hypothesis of the affect of gravity (rather the inertia of change) in theory creates a record (in the accounting sense) but need not horizon the few facts that support the economics driving the changability or rather the previous change but if one did not see modern forms as temporal entities but simply more diversifications then where the split occurs can not be yet recorded even if the fact is there. Gould did not.
