Figure 1

Boxplot showing the results of the Homoplasy excess test. The boxplot shows the distribution of bootstrap support values (%) for the Austrotilapiini. Each specimen was removed iteratively from the dataset (resulting in N = 63 experiments) and 1000 bootstrap replicates were calculated using ML. Outliers are shown as asterisks. Bootstrap support values clearly increased (from 56 initially to 86) after exclusion of T. mariae. This was the only that produced this effect.
