当女人同孩子们一起去收集食物的时候，男人则充当猎手的角色,他们常常要详细计划如何捕捉并杀死猎物。

Men on the other hand, decided in advance what animal they wanted to kill and then went looking for it. Once it was found - and killed - they returned home.
美国密歇根大学的丹尼尔克鲁格教授表示，这项研究将有助于解释，夫妇一起购物时为何会摩擦不断。
Professor Daniel Kruger of the University of Michigan said the study could be the answer to why there was so much conflict when couples shopped together.
克鲁格教授说，觅食是史前时代一个日常的社会行为,小孩子常常也参与其中,就像现在女性喜欢带着小孩子逛街一样。
Foraging was a daily social activity in prehistoric times and often young children were included, much like they are today when women shop, Prof Kruger said.

“她们还必须知道恰当的收割时机，以及某块收割的田地何时再次丰收。”
“They also must time harvests and know when a certain depleted patch will regenerate and yield good harvest
