To establish the rateofmutation, the team examined an area of the Y chromosome.
为了确定基因突变的速率,这个团队对他们Y染色体的某个区域进行了仔细的测定。

While most disease-causing mutated are found in humans at a rateof one in a few thousand to one in a few million people, founder mutation can occur at much higher rates.
虽然大多数致病突变在人类中发现的概率为千分之一到百万分之一,但基础突变发生的几率可能高得多。

That strongly suggests a faster mutationrate is at least part of the answer.
