Estimated expected ages of mutations in the tree of Fig. 1
| Mutation | T̂m using genetree | B | S | T̂m using (B, S) |
|---|---|---|---|---|
| 1 | 47,000 (35,000; 89,000) | 42 | 51 | 43,000 (37,000; 111,000) |
| 2 | 40,000 (31,000; 79,000) | 38 | 45 | 42,000 (36,000; 109,000) |
B is the number of individuals found in the sample that contained the mutation in question, and S is the number of segregating sites found within those individuals. The 95% probability intervals are obtained by using likelihood surfaces found in Fig. 3.
