Fossil Record Reliable, Study Says

A University of Chicago press release declares that the fossil record is reliable.  Susan M. Kidwell studied the record of bivalves as a function of their fragility and deduced that preservability of shells was only a minor factor in their observed abundance.  “In fact, if anything, variations having shells that seemed least likely to be preserved actually survived longer than forms with the toughest shells,” she said.  This does not mean the fossil record is complete; it merely means that the record is not biased toward those with the toughest shells.  “And because the bivalves cover such a wide range of shell types,” the press release ends, “these results suggest that shelly mainstays of the fossil record, such as snails, sea urchins and corals, may have comparably unbiased records, Kidwell said.”  Her report is published in the Feb. 11 issue of Science.1

Kidwell believes that this is good news for evolutionists, but only because it removes a possible source of sampling bias.  But how can it be good news?  It removes an excuse.  Evolutionists cannot claim that the gaps are due to harder shells surviving better in the rocks.  It means the gaps, the trade secret of paleontology, are real.
