Leaders in non - human society wield more power over followers than ours do , according to new finding published inTrends in Ecology & Evolution . Though , like humans , most – but not all – animal loss leader rise to the top based on case-by-case achievement .
The phenomenon of leadership and corporate action is common in societal species . Bottlenose dolphin alliances swim in seedcase with slews of penis , zebra harem travel together in herd , and meerkat last in kin group of about 20 drawn-out kin penis , for example . Yet , what all these leaders have in common – with each other and with humans – has n’t been analyse intensively . To look into , Jennifer Smithof Mills College in California and colleagues reviewed previous studies on leaders in four areas : cause , food acquisition , within - group conflict intermediation , and between - group interactions .
They compared 16 different small - scale societies , including eight human groups from Africa and North and South America and eight non - human groups : African elephants , bottlenose dolphin , chimpanzee , lions , meerkats , plains zebras , spotted hyenas , and white - faced capuchins . Variation in leadership can be measured in a few different ways , such as how one becomes a drawing card , how wide leadership is shared among others , how much big businessman is exerted , how potential they are to gain or mislay followers , and how much the leadership of one knowledge base ( like movement ) also lead in another ( like fight resolution ) .
Across species , leadership is generally achieved as someone age and put on experience . One far-famed animal exception is the spotted hyaena , where rank is inherited from the mother .
However , compared to people , animate being leader exert more power over their followers – though this is achieved through communicating and other passive ways , rarely compulsion . to boot , leaders among non - human mammals is more concentrated and domain - general : Those who resolve within - chemical group dispute , might also resolve between - group interaction , for example . man , on the other manus , tend to take on particularize function within our various groups .
Similarities between human and other mammal leaders in all probability reflect the organic evolution of apportion cognitive mechanisms governing dominance - subordination , alliance shaping , and decisiveness - making , the squad write .
