The relevance of persistence hunting to human evolution

Introduction

Based on the physiology and running performance of modern humans, Carrier (1984) suggested that endurance running to pursue prey was important in the evolution of hominins. Bramble and Lieberman (2004) provided a review of the morphological evidence suggesting that endurance running is a derived capability of the genus Homo, originating about two million years ago, and may have been instrumental in the evolution of the human body form. Recently, I provided data based on direct observations of persistence hunting (Liebenberg, 2006). Pickering and Bunn (2007) maintained that the behavioral pattern that selected for long-distance endurance running (ER) in the genus Homo remains unclear, but that it seems likely that hunting and scavenging contributed minimally, if at all. In particular, they maintained that nothing in my data contradicts the statement that persistence hunting (PH) with ER is extremely uncommon, even among people employing sophisticated tracking skills in the most ideal ecological environment for the behavior.

Here I argue that the fact that ethnographic data on PH are rare does not imply that it was extremely uncommon. Given the context within which PH was observed, the data that we have available are consistent with the possibility that it may have been common in the past. A simple form of PH may have contributed to the evolution of ER in early Homo. In addition, sophisticated PH may have contributed to the evolution of modern human intellectual abilities.

Context of recent observations

The statement that “over the course of 20 years, only two of the ER hunts observed by Liebenberg were spontaneous” (Pickering and Bunn, 2007: 436) is misleading. Firstly, I should clarify the context within which I conducted my field research over the course of 20 years. As an independent researcher (with no funding), I would have liked to have witnessed more hunts, but I simply did not have the financial means to do so. Between 1985 and 1990, and between 1992 and 1997, I was unable to visit

Ethnographic context

Pickering and Bunn (2007) pointed out that persistence hunting is ethnographically quite rare. One possibility is that most anthropologists working in the Kalahari simply did not see PH even when it did happen. While the bow-and-arrow draws attention to itself, PH does not require any special weapon that would prompt an anthropologist to ask questions about it. Unless they already knew about PH, they may never have thought to ask about it, and hunters may simply never have volunteered to talk

Historical context

Extensive fencing began in Botswana in the 1950s, devastating wildlife in the central Kalahari and making it increasingly difficult to hunt (Silberbauer, 1965, Child, 1972, Owens and Owens, 1985). In 1992, !Nam!kabe told me that wildlife was not as abundant as it was in the past, and that they were struggling to hunt.

/Gwi hunters' techniques in the central Kalahari during the period 1958–1966 included bow-and-arrow, snaring, catching springhare by means of barbed probes thrust into warrens,

Ecological context

Pickering and Bunn (2007) maintained that PH was restricted to very open and very hot habitats, such as the central Kalahari, portions of the American Southwest, and the interior of Australia (Lowie, 1924, Sollas, 1924, Schapera, 1930, McCarthy, 1957, Lee, 1979, Silberbauer, 1981, Steyn, 1984). Pickering and Bunn (2007) further maintained that arid environments where ground is sparsely covered with vegetation do not characterize the habitats reconstructed for early Homo, while savanna-woodlands

Evolutionary hypothesis

Pickering and Bunn (2007) were reluctant to assign to early Homo the impressive tracking skills of the Kalahari San. On the other hand, Lieberman et al. (2007) maintained that the reasonable null hypothesis should be that early Homo had the cognitive skills necessary to track. Even among modern trackers, however, different levels of tracking can be distinguished that require fundamentally different cognitive abilities.

A simple form of PH may have first developed in easy-tracking terrain, such

Conclusion

As pointed out by Lieberman et al., 2007, Pickering and Bunn, 2007 made several flawed assumptions. Persistence hunting may have been more common before the invention of the bow-and-arrow or the domestication of dogs and horses. The apparent scarcity of ethnographic records of PH does not imply that PH was rare—it could simply be that anthropologists who were able to observe PH were rare. Over the last 50 years, hunter-gatherers in the Kalahari have experienced drastic changes, and the recent

      Both approaches obtained a good number of records, equivalent to that of the camera traps, and better represented the diversity of primates. Including the experience of local populations in research activities, participatory research, and citizen science have many advantages (Constantino et al., 2014; Eaton et al., 2017; Liebenberg, 2008; Pocock et al., 2018). Indeed, our findings corroborate those reported by Danielsen et al. (2005) regarding the advantages of including local monitors in data collection alongside local experts and trained scientists.

      This ability to regulate temperature is very important for humans as even a small increase in body core temperature to 40.5 °C can result in heat stroke [42]. This in turn has led to humans not only being the “naked ape”, but also the sweatiest primate, and an effective persistence hunter [43–45]. In turn, if our human ancestors lost their thick terminal hairs, and they were replaced with fine vellus hairs, it would be expected that the attached sebaceous glands would undergo a similar proportional atrophy and become small and vestigial as is observed on the arm.

      Although the above results may be interpreted as suggesting frequent running behavior in H. erectus, current behavioral evidence on modern hunter-gatherers involved in endurance running cannot unambiguously confirm such interpretation. Modern hunter-gatherers have been documented to practice persistence running when hunting, which is characterized by short periods of run interspersed with walking and tracking (Liebenberg, 2006; Lieberman and Bramble, 2007). Such an activity pattern is different from the continuous running of cross-country runners and probably implies different loading patterns in the leg bones.
