evolutionary clock

基本解释

They then used a so-called "molecular clock" technique to put dates on the evolutionary story of rice.
之后，科研人员使用一种叫做“分子钟”的技术将遗传数据置入水稻的进化史中。
With better measurements of mutation rates, we could improve the calibration of the evolutionary clock, or test ways to reduce mutations, for example.
如果能够更好的掌握测量突变速率，我们将能够改善进化时钟的标准，或者测试一些方法减少突变。
As a molecular clock and genetic marker, superoxide dismutase has been widely used in evolutionary studies, population genetics, and identification of different strains in the same species.
因此，超氧化物歧化酶作为分子钟或分子标记已被广泛应用于生物进化研究、群体遗传结构分析以及品系鉴定。
