Size matters? Testicle size linked to nurturing
John Bacon, USA TODAY
Men with smaller testicles are more likely than their well-endowed brethren to be involved in the care of their toddlers, anthropologists at Emory University report.
The higher the testosterone levels and larger the testicles, the smaller the amount of direct paternal caregiving by dads as reported by parents in the study.
"Our data suggest that the biology of human males reflects a trade-off between mating and parenting," Emory anthropologist James Rilling, whose lab conducted the research, reports on the Atlanta university's website. The Proceedings of the National Academy of Sciences published details of the study this week.
Rilling noted that "life history theory" holds that evolution optimizes use of resources toward mating or parenting to generate the largest number and healthiest offspring.
当然这也可能是伪科学了。但仔细想想也有道理。为什么人类进化出来一个“男主外,女主内”的家庭模式?
假如这个观察是正确的,那也可能有不同的原因。一个就是阳刚的男人对待在家里做家务照顾孩子有激素性的抵制,这样肯花很多时间照顾孩子的父亲就往往是“不够阳刚”的。另外一个原因,就是婴幼儿为了自己的生存和福祉,会诱导父亲身体产生化学变化。父亲与孩子花的时间愈多,受到的影响也越大。说是“化学阉割”过分了,但化学抑制还是很有可能的。
哈哈,这就成了典型的“鱼与熊掌”了。国内常听说的“小子不坏,姑娘不爱”也就很有道理了。
