摘　　要：介绍了利用MrBayes进行分子钟定年的研究概况和程序。利用一个整合分子序列和形态特征的膜翅目昆虫的数据,展示了两种现代方法:全证据定年和节点定年,并对这两种方法的相似点和不同之处进行比较和讨论。此外,还用无分子钟的方法对同一数据进行分析,并与分子钟定年法进行比较。This paper provides an overview and a protocol of molecular clock dating using MrBayes.Two modern approaches,total-evidence dating and node dating,are demonstrated using a truncated dataset of Hymenoptera with molecular sequences and morphological characters.The similarity and difference of the two methods are compared and discussed.Besides,a non-clock analysis is performed on the same dataset to compare with the molecular clock dating analyses.
