An MRCA is the _most recent_ ancestor of a set of tips. For example, in the following tree:\r\n\r\n```(((A,B)1,C)2,((D,E)3,F)4)5;```\r\n\r\nthe root (denoted with `5`) is _an_ ancestor of A and B, but node `1` is _the most recent_ ancestor. MRCA statements are used to identify specific nodes to place constraints on the ages of nodes (maximum or minimum ages). Only two descendant tips need to be specified. For example, node `2` is the ancestor of tips A, B, and C, but it can be specified with either the tip pairs `A and C` or `B and C` (but not `A and B`, as that identifies node `1`).\r\n\r\nThe config file needs to be plain text.\r\nHTH."}}
