一篇论文认为,在玻利维亚提斯曼原住民中,遭遇过伴侣暴力的女性平均生育子女的数量比没有遭遇过暴力的女性要多。相关研究8月7日在线发表于《自然—人类行为》。

尽管伴侣暴力会对一个人造成直接伤害,但这种现象仍普遍存在。许多行为因素和社会经济因素与此类暴力有关,包括教育水平、妇女权利和酒精或药物滥用等。虽然这些因素是伴侣暴力的重要触发因素,但人们仍不确定是否存在潜在的演化机制。

法国图卢兹高等研究中心的Jonathan Stieglitz、美国加利福尼亚大学圣巴巴拉分校的Michael Gurven及合作者采访了105名来自5个玻利维亚亚马孙提斯曼原住民村庄的异性恋女性。提斯曼文化没有强烈的暴力历史,男性不具有社会支配地位。他们发现,在婚姻中遭遇过伴侣暴力的女性平均生育子女的数量比没有遭遇过暴力的女性要多。无论夫妻双方在童年时期是否被暴露在伴侣暴力之下,或男方是否存在针对其他男性的暴力历史,这种模式都是成立的。过去的研究已经表明,平均而言,提斯曼女性偏好的家庭规模小于男性偏好的规模,研究者认为当夫妻双方对理想的家庭规模产生分歧时,伴侣暴力可能会增加生育率。

该研究的关注重点不仅有伴侣暴力的终极驱动因素或演化驱动因素,也有经济和社会压力等近因机制或动机,还有对暴力的态度——所有这些都可能是演化适应动机的基础。研究者总结表示,了解伴侣暴力对伴侣以及家庭的演化成本和收益,或有助于采取系统性措施进行预防
