Gaps in fossil teeth: Saltations or sampling errors?

All evolutionists accept that there are gaps in the fossil record. To some, gaps are data: they mark sudden transitions, unlikely to be preserved, between one species and its descendants that have arisen by a brief genetic revolution within an otherwise stable lineage. However, recent studies of sediment gain and loss show that few fossil beds can be complete enough to give details of the process of speciation, so that most gaps are gaps, and nothing more. Differences in the perception of time and sampling completeness mean that paleontologists and geneticists see the rate and pattern of evolution in different ways. Just how misleading each view may be is seen by analysing the laws of life governing change in living populations using the limitations intrinsic to studies of past times; and by a new insight into the details of species formation now emerging from some remarkably complete primate fossil sequences.
