addresses apparent absence of transitional forms
gaps in geological strata
imperfection of paleontological evidence
incompleteness of the fossil record
unequal exploration of geological formations
unequal preservation of organisms
argues that absence of evidence is not evidence of absence for transitional forms
that fossilization is a rare event
that geological formations represent only small, broken portions of Earth history
that geological time is vast compared to preserved strata
that many intermediate varieties existed only locally or briefly
that many species existed without leaving fossil traces
that soft-bodied organisms are less likely to fossilize
that terrestrial organisms are less likely to fossilize than marine organisms
that the fossil record is extremely imperfect
