Prehistoric marine mammal hunting is of interest to archaeologists wor
ldwide because these animals were exploited by a wide range of coastal
societies. Sorting out file roles of particular groups of fauna in pr
ehistoric economies requires detailed attention to the analysis of the
entire faunal assemblage. Although marine mammals typically provided
large quantities of fat a,ld protein and were desirable pi ey, they we
re not always central to the diets of the groups that exploited them,
particularly in temperate zones. To evaluate effectively rite importan
ce of marine mammal exploitation, scholars should calculate the relati
ve contribution of these animals to the economy, identify changes in h
unting techniques, determine the relationship between fauna and other
aspects of society, assess changing environmental conditions, and cons
ider alternate explanations for those relationships. A large body of r
esearch research oil the northern Channel Islands of California demons
trates that fishing was relatively more important than marine mammal e
xploitation in subsistence and in stimulating sociopolitical and techn
ological developments. Recent attempts to credit marine mammal hunting
as a driving force in the invention of the plank canoe and the evolut
ion of a chiefdom in the Santa Barbara Channel area misunderstand envi
ronmental factors and site histories in this region. Rather than assum
ing that a pan-Pacific Coast set of traditions existed to exploit thes
e taxa, we see evidence of local and regional differences rooted in va
riable cultural settings, physiographic and oceanographic conditions,
and available technologies. Data fr om the Santa Barbara Channel are u
sed to explore the relationships among marine mammal use, sociology ca
l change, and environmental change.
