Natural Selection and History

An interesting looking paper has just appeared online by John Beatty and Eric Cyr Desjardins that looks at the importance of history in determining form. The abstract reads:

In ?Spandrels,? Gould and Lewontin criticized what they took to be an all-too-common conviction, namely, that adaptation to current environments determines organic form. They stressed instead the importance of history. In this paper, we elaborate upon their concerns by appealing to other writings in which those issues are treated in greater detail. Gould and Lewontin?s combined emphasis on history was three-fold. First, evolution by natural selection does not start from scratch, but always refashions preexisting forms. Second, preexisting forms are refashioned by the selection of whatever mutational variations happen to arise: the historical order of mutations needs to be taken into account. Third, the order of environments and selection pressures also needs to be taken into account.

Haven?t had a chance to read it yet, but a copy is sitting on my ?To Read? pile.
