But this evolutionary mechanism combining dissymmetry, anatomy, and chance does not provide an adequate explanation of why right-handedness should have become predominant.

但是这种结合了不对称、解剖学和偶然性的进化机制并不能提供一个充分的解释来说明为什么右利手应该成为优势。

Here, the evolutionary theory must defer to a theory based on an explicit developmental mechanism that can favor either right-handedness or left-handedness.

在这里，进化理论必须遵从一种基于明确的发展机制的理论，这种机制既可以支持右撇子，也可以支持左撇子。

这种结合不对称、解剖学和偶然性的进化论机制并未提供一种充分的解释，以说明蜗牛的右旋何以会成为主要的旋向。

The researchers say their findings add to the evidence that the evolutionary forces that cause right- and left-handedness are independent of culture.

They suggest that because left-handedness is relatively rare it provides certain advantages over those who are right-handed, such as in solo and group fighting.

This brazen high- handedness, based on nothing more than a judges whims about what he thought was right for the people, was too much even for his peers to stomach.
