ChronoMPL Molecular Dating With Mean Path Lengths in ape. To illustrate the breadth and frequency of calibration types currently employed, we conducted a literature survey of over 600 articles published from 2007 to 2013. This function estimates the node ages of a tree using the mean path lengths. B. Vinnersten, A. and Bremer, K. 2002 Phylogenetic dating with confidence.
