Reading the past
tool technology, demography and subsistence, archaeologists
have also applied evolutionary approaches to rather ‘ideotech-
nic’ domains such as ceremonial architecture, carved mon-
uments, ceramic style and Upper Palaeolithic cave painting
(Ames 1996; Bettinger et al. 1996; Graves and Ladefoged 1995;
Mithen 1996a; Neiman 1995; 1997; Rindos 1986; Shennan
and Wilkinson 2001). For example, Shennan has recently at-
tempted to use models of population size and genetic trans-
mission of information to explain Upper Palaeolithic/Late
Stone Age cultural innovations such as the emergence of per-
sonal adornment, musical instruments, complex forms of art,
and new stone, bone, antler and ivory tools. Briefly, Shennan
uses simulations to show that cultural innovations result in
greater adaptive fitness for individuals in large interacting
populations as opposed to small ones. Thus, although the first
modern humans were capable of cave painting and musical in-
novation, these innovations did not ‘catch on’ (were not suc-
cessfully transmitted) until the size of interacting populations
reached the level at which such innovations became adaptive –
approximately 50,000 years ago. Since Shennan treats cul-
tural innovations as mutations, and since mutations are only
transmitted to others when the population is large enough,
there is no room in his account for intentionality or meaning.
Shennan appears to understand that innovations such as mu-
sical instruments are not ‘adaptive’ in a strict biological sense,
so he instead uses the term ‘attractive’. However, it is difficult
to understand what sort of innovation would be considered
attractive when these innovations have no meaning.
Evolutionary psychology takes a somewhat different ap-
proach. Mithen (1996a, pp. 80–2; 1998a, p. 10) uses a holis-
tic, evolutionary, ecological perspective on the ancient mind.
This approach attends to all facts of ancient life – art, reli-
gion, economy – and does not divorce cognition from the
rest of society. At the centre of Mithen’s explanations of
past behaviour is a rather progressive understanding of adap-
tation which takes into account individual decision-making
and the importance of creativity (1996a; 1998a). Mithen’s
interdisciplinary focus has produced a number of ambitious
