For those fans of human evolutionary research news, you will be well aware of the lack of research into the role insects played in the diet of hominins over the past 6 or so million years.
This topic was addressed back in 2001 in the chapter of an academic volume by William McGrew of the department of Archaeology and Anthropology, University of Cambridge. Since then nothing has been done to address ways in which such an investigation could be conducted. What can be done to address this? Look at what we………..modern primate diets and the role insects play in their diets from the human to the Orang-utan. Let’s then look at the earliest evidence for hominin consumption of insects. South Africa has nabbed that prize, thus far. The Lower Palaeolithic sites of Swartkrans, Sterkfontein and Drimolen contained hominin fossil bone tools with wear patterns similar to those wear patterns you find on sticks used by Chimps to fish for termites. Fossil remains of Paranthropus robustus were found at these sites and the evidence suggests they were feasting on termites.
Examining the fossil evidence is one focus, but there are others including, lithics, residues, dental microwear, stable isotopes, DNA and coprolites (Fossilised shit…..basically). The dental microwear is quite problematic, because you have to take note that the tooth has been in the earth for millions of years (2.4 million years for the earliest Paranthropus specimen). Stable isotopic research is the much more promising of the topics discussed in William McGrew’s latest paper for the Journal of Human Evolution.
