evolutionary clock

基本解释

They then used a so-called "molecular clock" technique to put dates on the evolutionary story of rice.
之後，科研人員使用一種叫做“分子鍾”的技術將遺傳數據置入水稻的進化史中。
With better measurements of mutation rates, we could improve the calibration of the evolutionary clock, or test ways to reduce mutations, for example.
如果能夠更好的掌握測量突變速率，我們將能夠改善進化時鍾的標準，或者測試一些方法減少突變。
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，超氧化物歧化酶作爲分子鍾或分子標記已被廣泛應用於生物進化研究、群躰遺傳結搆分析以及品系鋻定。
