Diet and the Neanderthals

The ultimate goal of paleoanthropological studies is to develop the most accurate and exhaustive portraits possible of our extinct human relatives, and of the history by which we became what we are. This endeavor includes, in the first place, the essential processes of establishing the basic parameters of hominid diversity, and of elucidating the potential evolutionary relationships among the components of that diversity. But our efforts clearly need to go farther than this; for the overall picture of human evolution is quite evidently incomplete without consideration of early hominid lifeways, and of how now-vanished hominid species interacted with their environments. Among the most important interactions of this kind is, unquestionably, feeding behavior and the expression of such behaviors in diet. For, at least short of breathing, feeding is the most fundamental of all the subsistence activities in which a terrestrial species can engage. And we will never be able to claim to understand the lifeways of ancient hominids without at least some insight into how they sustained themselves. Self-evident as these remarks might be, however, they should not be taken to imply that--especially among eurytopes such as hominids--diet can, or should ever be regarded as, monolithic, or as an intrinsic property of any species. Nor do they mean that we can ever look upon hominid populations as "adapted" to particular food resources. Indeed, primates in general are remarkably varied in the diets that may be chosen by different populations of the same species, both seasonally and geographically [see, for example, the review of dietary variation among Malagasy strepsirhines in Tattersall, 1982]. Rather, amongst most if not all-living primates that have been studied, it appears--not surprisingly--that the factor, which most importantly controls immediate dietary intake, is the spectrum of potential food resources available within the local environment. Not to put too fine a point on it, most primates are opportunists.
