Asyncritus, your last example doesn't make much sense. Please could you be more clear.
And besides, fossil records do not neccesarily have to illustrate a gradual chain of fossils that reflect gradual change. This is a misconception.
Some changes may happen that are random and rapid. For example, the theory of 'punctuated equilibrium', proposed by elderidge and gould in 1972, suggests that localised speciation events can occur in apparently stable sexually reproducing population.
