Have aggression and violence been ramped up in human evolution or dialed down? This sounds like a question that empirical research might have settled long ago, but it remains strangely contentious. In PNAS, Richard Wrangham (1) proposes that debates persist because too many evolutionary anthropologists mistakenly conceive of aggression as unitary and that a well-established distinction between “proactive” and “reactive” aggression holds the key to a resolution.

分区侵略

侵略和暴力是否在人类进化中得到加强或减少了？这听起来像是一个经验研究可能早就解决了的问题，但它仍然有争议。在PNAS中，Richard Wrangham（1）提出辩论之所以继续存在，是因为太多的进化人类学家错误地将侵略视为统一的，而“主动”和“反应”侵略之间已确立的区分是解决方案的关键。
