Abstract
We present a simple Monte Carlo method for estimating the age of the m ost recent common ancestor (MRCA) of a sample of DNA sequences. We sho w that Templeton's (1993) estimator of the age of the MRCA based on th e maximum number of nucleotide differences between two sequences in a sample is inaccurate, and we demonstrate the new method by reanalyzing a sample of DNA sequences from human Y chromosomes and a sample of hu man Alu sequences.
