A more precise characterization of hunter-gatherer nutrition, however, requires an estimation of the relative quantities of animal and plant matter consumed (P:A ratio), as well as their types and average nutritional content. Early estimates of P:A ratios for typical hunter- gatherer tribes indicate diets composed of 65% plant matter and 35% percent animal tissue (2). 0762病弱名無しさん (ﾜｯﾁｮｲW 11ad-xYo4 [106.168.99.231])2016/08/11(木) 00:25:55.37ID:g5qUY8z80 More recent analyses based on Murdock's Ethnographic Atlas (3) have, in contrast, suggested that most (73%) of hunter-gatherer societies derived >50% of their calories from meat (including wild game and fished foods), while only 14% of societies derived >50% of their calories from plants (4). Extreme P:A ratios of 1:4 or 1:9 (respectively, the Ache of Paraguay (5) and Alaskan Eskimo tribes (6)) have been described, consistent with the hypothesis that humans are adapted to consuming large quantities of animal flesh. Naturally, variability of P:A subsistence ratios among hunter-gatherers was quite high, depending on latitude, climate, location, and seasonal variations in the food supply (1). Furthermore, hunter-gatherer P:A ratios are not likely to be completely representative of those consumed by Paleolithic humans, as modern tribes have been relegated to marginal habitats, and the herds of large ungulates on which Paleolithic humans probably depended have been largely depleted over the course of the last few thousand years. 0763病弱名無しさん (ﾜｯﾁｮｲ 5abf-MTuc [223.29.176.54])2016/08/11(木) 06:17:29.30ID:5D7pggdH0 一致した見解？ また捏造？ そんなだから王城に勝てないんだよ、捏造

our unique ratio of brain to gut size is the result of a profound energetic shift that began with the first hunter-gatherers, in which early Homo essentially traded off large guts for large brains by switching to higher quality diets.
