本文考察了目前采用的估计同源蛋白质序列间进化距离的方法的缺陷，并提出了几个新的计算公式，它们考虑了氨基酸位点间显然存在的替代速率的差异。

The karyotype resemblance-near coefficient is0.9692 , evolutionary distance of Jianbai Xiang Pig is0.0313 , it indicates relative extent is high .

剑白香猪两品系的核型似近系数为0.9692，进化距离为0.0313，表明亲缘程度很高。

And if evolutionary distance is out of proportion to evolutionary time , it probably suggests that this phenomenon should use relative substitution rate as parameter and can be explained by new-Darwinism .

用进化距离重建的系统树事实上支持中性学说；若进化距离与进化时间显著地不存在线性关系的话，则可选用替代率，该情况表明中性学说不适用，似更倾向于新达尔文主义。
