A field of study of two hunter - collector high society located half a world apart has launch similarity in the shape of their societal networks . These structures have keen natural selection time value during hard times , and commonalities with societies where the interconnecting web is worldwide , rather than a food WWW . Having lived for so much of our history in surroundings like this , such structure may have put down the foundations for our networks in a digital age .
We have plenty of reason to link up with other people , but our original needs were for nourishment and safety . " No other apes partake in food for thought to the extent that humans do , " saidDr Andrea Miglianoof University College London in astatement .
Migliano conduct a study , reported inCurrent Biology , of the Agta the great unwashed in the Philippines and the Mbendjele people in the Republic of Congo . Neither conducts their own Department of Agriculture , although each trade wind foods they catch or pile up with neighbors who do train crop .

Migliano map the food for thought sharing web . In each case , individuals were part of a household unremarkably made up of five to six masses . Three to four house would get along together in a “ clustering ” to share food frequently , while also being part of a wide camp , which could be relied on for musical accompaniment if hardship strike an individual household . “ In larger camps , there are more clusters rather than larger clusters , ” the paper cover .
" Despite being from different continents and living in very different ecologies , both group of hunter - gatherers had a strikingly similar social organization , " said first authorMark Dyble . " Cooperation and peculiarly food share-out are essential for survival in a hunting - and - gathering economy , "
man need this level of communion , the authors debate , because we have such long childhood when we can not resist for ourselves , and comparatively scant period between birthing , see to it parent are often supporting substantial numbers of baby . Moreover , the paper notes , “ We have moved to a dietary niche that often involves the development of difficult to acquire foods withhighly variable take rates . ”
The only way to get through menses where it is unmanageable to secure food is to cooperate , the authors suggest , and despite major difference of opinion in culture and the foods being collected , standardized structures have proven to provide the best backing .
Nevertheless , the systems were adaptable for the circumstances . Among the Agta , who live primarily on fish and food accumulate in the intertidal zone , camps average 63 person . The Mbendjele , whose food is more disperse , average just 41 people to a refugee camp .
The authors pass over every meal consume over a period of more than three months , observing that 61 pct of the gram calorie squander by the Mbendjele were produced within the household , while among the Agta 74 per centum of intellectual nourishment was make in - house . Although most of the rest came from closely related family , the spacious ingroup cater a buffer zone that could be drawn upon in times of need .
Despite decades of anthropological study of traditional lodge , Dyble say this is the first to quantify how societal internet shape food gathering and dispersion
Dyble concluded : " The proverb that ' it takes a small town to raise a child ' is certainly true for Orion - gatherers , who , without food for thought sharing to extenuate the day - to - 24-hour interval shortfalls in foraging , could simply not live . "
