The phylogenetic tree was constructed using maximum evolution approach in Mega. The negative selection sites were analyzed by using Datamonkey. There is an apparent 30 bp nucleotides deletion mutation in homonids FKN comparing to that of Old World Monkeys besides other point mutations. Homology of nucleotide sequence between human and chimpanzee, gorilla, orangutan, gibbon, macaque and leaf monkey is 99.2%、98.4%、98.1%、96.5%、95.9% and 93.8% respectively. Homology of amino acid sequence of them is 98.5%、98.0%、97.7%、94.7%、93.7% and 90.5% respectively.

序列分析发现人猿超科较旧大陆猴FKN基因除了有散在的点突变外，还有一明显的30bp的核苷酸缺失突变；人FKN基因序列与黑猩猩、大猩猩、红毛猩猩、长臂猿、猕猴和叶猴的同源性分别是99.2%、98.4%、98.1%、96.5%、95.9%和93.8%，由此推导的氨基酸序列同源性分别是98.5%、98.0%、97.7%、94.7%、93.7%和90.5%；FKN基因进化树表明人与黑猩猩关系更近，FKN基因进化和通常认为的物种进化一致；Datamonkey分析结果显示FKN存在3个负选择位点53Q、84D、239N。

Single nucleotide polymorphisms are the most common form of human genetic variation, with millions present in the human genome.
