South Africa has a wealth of archaeological and
palaeoanthropological material, of regional, national and
international importance.
My research: “understanding past animal and human life in their
environmental contexts in the Western Cape” focuses on the past half
million years. The aim is to create greater understanding of how
Stone Age people interacted with the animals around them and how
they adapted their behaviour to the changing environments and
seasons in which they lived over the millennia. Results also provide
information on the changing bio-diversity of the animals themselves.
Bird and mammal bones from archaeological and palaeontological
sites provide the primary source of the information I seek.
Interpreting the bones can be complex, however, since they may have
been brought to a site by any one (or more) of a range of mammalian
carnivores and scavengers and birds of prey. To help unravel such
puzzles, the ancient material is compared with samples of bones I
have collected from modern hyaenas, jackals and porcupines and the
nests of eagles and hawks. This type of study, known as taphonomy,
helps us to identify the accumulator of the ancient material and to
gain a clearer picture, for instance, of whether the samples we are
studying resulted from human behaviour or that of another
accumulator or accumulators.
Another project, which has thrown light on the time of year when
ancient people exploited different seabird species, is the monthly
survey of beached seabirds and mammals I have conducted on a 15 km
stretch of beach in the West Coast National Park for over 29
years. It is one of the most extensive long-term data sets for birds
in South Africa and is one of the best designed surveys of its kind
in the world. The surveys allow us to monitor mortality in response
to biological and physical oceanic conditions and human
interventions.
I currently work with colleagues from Stanford University, the
University of California Davis and the University of Cape Town.
