为什么左撇子是少数?

The reason so few people are left-handed is because humans have evolved to make it easier to work together as a society, researchers say.

Abrams, lead author of the Northwestern study.

The most important factor for an efficient society is a high degree of cooperation.

In humans, this has resulted in a right-handed majority.

”研究人员称，左撇子之所以如此之少，是因为人类的进化使整个社会更容易合作。

西北大学这项研究的主要作者丹尼尔·m·艾布拉姆斯说:这种动物的社会性越强，也就是合作受到高度重视的地方，那么它们的总体倾向就会偏向一边。

”一个高效社会最重要的因素是高度的合作。

在人类中，这导致了多数人是右手。
