Je ne suis pas certain de cela, au contraire, l'humanité s'est nourrie majoritairement de fruits et de plantes au cours de son histoire. Même lorsque nous étions chasseurs-cueilleurs, la viande ne représentait qu'un apport intermittent, même si crucial

Quote:
Lee’s (1968) analysis was widely misinterpreted over the
next 32 y to mean that gathered plant foods typically provided
the major food energy (65%) in worldwide huntergatherer
diets, while hunted animal foods made up the
balance (35%; Beckerman, 2000; Dahlberg, 1981; Eaton &
Konner, 1985; Milton, 2000; Nestle, 1999; Zihlman, 1981).
As we have previously pointed out (Cordain et al, 2000a, b),
this general perception is incorrect because fished animal
foods must be summed with hunted animal foods in the
analysis of the ethnographic data to more correctly evaluate
dietary plant to animal subsistence ratios (ie the percentage
of energy contributed by plants vs animal foods). Our analysis
(Figure 1) of the Ethnographic Atlas data (Gray, 1999)
showed that the dominant foods in the majority of huntergatherer
diets were derived from animal food sources. Most
(73%) of the world’s hunter-gatherers obtained >50% of
their subsistence from hunted and fished animal foods,
whereas only 14% of worldwide hunter-gatherers obtained
>50% of their subsistence from gathered plant foods. For all
229 hunter-gatherer societies, the median subsistence dependence
upon animal foods was 66 – 75%
. In contrast, the
median subsistence dependence upon gathered plant foods
was 26 – 35%. Further, we re-analyzed Lee’s original subsample
(n¼58) of the Ethnographic Atlas and obtained results
almost identical to those of our study of the entire 229
hunter-gatherer societies (Cordain et al, 2000b). The subsistence
dependence upon hunted and fished animal foods was
66 –75% (median value), whereas the median value for
gathered plant foods was 26 – 35%.



Ca ne concerne que les peuples chasseurs-cueilleurs actuels, non pas nos ancêtres, mais je ne vois pas bien ce qui serait différent.

L'humanité a donc vécu majoritairement sur de la viande et du poisson, des fruits, des noix, des baies et des racines.
Que des choses qui peuvent se cultiver comme/au sein d'un système agroforestier Wink
