Qesem CaveThe article didn't specifically mention cooking remains dating as far back as 400,000 years ago and it focused on remains from 200,000 years ago. There are fewer traces of fires in the soil strata that date back earlier than 200k years ago. Since I thought cooking was already widely accepted as dating back to 250,000 years ago, that 200k figure didn't phase me. I was more interested in the fact that here is more evidence that hominids were butchering and eating large quantities of meat hundreds of thousands of years ago and that the way meat was butchered changed in at least one area at around 200k years ago, and if this evidence is buttressed by other evidence, it may cause scientists to decide that meat eating was prevalent long before advanced cooperation was. But you should read the materials yourselves and draw up your own hypotheses if you wish.
Since people seem more interested in the cooking/fire aspect, here is more on that:
Fire
http://en.wikipedia.org/wiki/Qesem_Cave
The Qesem Cave contains one of the earliest examples of regular use of fire in the Lower Pleistocene. Large quantities of burnt bone, defined by a combination of microscopic and macroscopic criteria, and moderately heated soil lumps suggest butchering and prey-defleshing occurred near fireplaces.
10-36% of identified bone specimens show signs of burning and on unidentified bone ones it could be up to 84%. Such heat reached 500 degrees C.[5]
Hunted prey
Bones from 4,740 prey animals have been identified. These are mostly large mammals such as fallow deer (73–76% of identified specimens), aurochs, horse, wild pig, wild goat, roe deer, wild ass and red deer. Tortoise and a rare rhinoceros remains have also been found but no gazelle bones.[6]
These animal bones show marks of butchery, marrow extraction and burning from fire. Analysis of the orientation and anatomical placements of the cut marks suggest meat and connective tissue was cut off in a planned manner from the bone.[6]
Deer remains are limited to limb bones and head parts without remains of vertebrae, ribs, pelvis, or feet suggesting that butchery was selective in regard to the body parts that had been carried to the cave following initial butchery of the animal carcasses elsewhere.[6]
Moreover the presence of fetal bones and the absence of deer antlers implies that much of the hunting took place in late winter through early summer. At this time the need for additional fat in the diet would have been made them particularly important food. The excavators described this as “prime-age-focused harvesting, a uniquely human predator–prey relationship”. [6]
Re: the selection of deer heads and limbs: It sounds like that for the lean animals like deer, the hunters were keeping the brains ("head parts") and marrow ("limb bones"), and perhaps some choice organs, and were discarding much of the meat. This confirms what Ray Audette and others have proposed about Stone Agers selecting the fattiest parts and discarding some of the lean, which would probably make Cordain and Eaton's low-fat calculations based on whole carcasses somewhat misleading. I had suspected that Audette was right about the diet of Stone Agers being high fat and Cordain/Eaton wrong, and it looks like we've got some hard data to support that. However, for larger, fattier animals, like aurochs, perhaps Stone Agers did not discard the lean parts, because this article only mentions deer remains revealing such selection. I wonder what the % of calories that come from fat was for a whole auroch carcass.
Evidence for habitual use of fire at the end of the
Lower Paleolithic: Site-formation processes at Qesem Cave, Israel
http://www.tau.ac.il/humanities/archaeology/info/ran_barkai/HabitualUseofFireJHE2007.pdf
A number of other Lower Paleolithic sites, including some Acheulo-Yabrudian cases, have yielded burnt materials that have been interpreted as hearth traces (Tsatskin, 2000; Meignen et al., 2001; Goren-Inbar et al., 2004; Rolland, 2004; Preece et al., 2006). The findings at Qesem Cave extend beyond the identification of burnt remains in the sediments, however, in that the archaeological and geological evidence supports a ‘‘residential base’’ scenario. Hearths formed hubs around which other activities were carried out in the cave; use-wear damage on blades and blade tools in conjunction with numerous cut marks and impact fractures on large bones indicate an emphasis on prey butchering, defleshing, and marrow extraction in the vicinity of fireplaces. Hominin use of fire during the late Lower Paleolithic at Qesem Cave seems to have been grossly similar to the behavioral patterns observed in later Middle Paleolithic populations in the Levant region.
The multidimensional approach advocated by this study illustrates the difficulties for field identification of burnt materials and matrix, particularly in the absence of visible charcoal. Under favorable preservational conditions, however, the microscopic analysis of intact structures can reveal the true nature of the sediment and whether or not there is wood ash (e.g., Weiner et al., 1998; Goldberg et al., 2001).
