Darwinism "Has Pretty Much Reached the End of Its Rope"

An interesting paper was recently published by David Depew and Bruce Weber in the journal Biological Theory. The paper bears the title "The Fate of Darwinism: Evolution After the Modern Synthesis." Its abstract summarizes the article's contents:

We trace the history of the Modern Evolutionary Synthesis, and of genetic Darwinism generally, with a view to showing why, even in its current versions, it can no longer serve as a general framework for evolutionary theory. The main reason is empirical. Genetical Darwinism cannot accommodate the role of development (and of genes in development) in many evolutionary processes. We go on to discuss two conceptual issues: whether natural selection can be the "creative factor" in a new, more general framework for evolutionary theorizing; and whether in such a framework organisms must be conceived as self-organizing systems embedded in self-organizing ecological systems.

This paper is interesting in at least two respects. First, there is the curious use of the word "Darwinism" to describe the modern evolutionary synthesis. It is frequently asserted by our critics that "Darwinism" is a pejorative term invented by creationists and proponents of ID as a form of derision. The term, however, is used widely in the mainstream scientific literature -- albeit not always in a consistent manner. The authors define "Darwinism" thus:

Darwinism refers to its author's proposed causal explanation of evolution -- natural selection -- and to theories in which this process plays the dominant role in evolution, including human evolution.

The second point of interest is the paper's claim that "Darwinism in its current scientific incarnation has pretty much reached the end of its rope." Furthermore, as the authors argue,

...it is largely because Lamarckism, saltationist (sudden) mutationism, and inner-driven orthogenesis, to name the most enduring alternative traditions in evolutionary biology, failed to become mathematized empirical sciences with at least a foothold on value-neutrality that Darwinism still rules the evolutionary roost.   Continue at Darwinism
