Abstract
In 2007, David S. Wilson and Edward
O. Wilson (27) pointed out that, Richard
Dawkins had admitted that, contrary to what he
had claimed in his book The Selfish Gene (1976)
(7), the idea that only the gene is a fundamental
unit of selection cannot be used as an argument
against the notion of group selection. This elicited
a sharp denial from Dawkins (30), which
was followed by an explanatory reply by Wilson
and Wilson (33) and another vehement denial by
Dawkins (34). I analyse the prehistory of this surprisingly
complex and convoluted dispute and
subsequently disentangle it. My conclusion is that
much of it is based on a series of misunderstandings.
First, Wilson’s and Wilson’s (27) original
interpretation of Dawkins’ selfish gene argument
was incorrect. Second, in their explanatory reply
(33), they distinguished between two kinds of
group selection: the idea that groups can be units
of selection (theoretical group selection) and the
idea that group selection plays a functional role in
evolution (functional group selection). They
clarified that their claim concerned theoretical
group selection, not functional group selection.
Third, that clarified claim was correct and not
correct. It was incorrect because Dawkins has
never explicitly acknowledged that he had erred
by developing his selfish gene theory as an implicit
argument against this kind of group selection.
However, the distinction that he made, by 1978,
between two kinds of unit of selection, replicators
(genes) and vehicles (somas), does imply such an
acknowledgment since it holds that groups can be
units of selection (vehicles). In this important
sense, Wilson’s and Wilson’s clarified claim (33)
was correct. Fourth, Dawkins’ second denial (34)
concerned functional group selection, not theoretical
group selection.
