Figure 11.11 A strict consensus of 25 fundamental trees derived from the analysis of an expanded
version of Ahlberg and Clack’s (1998) dataset with all characters unweighted and unordered; B,
strict consensus of five fundamental trees obtained after reweighting characters by their rescaled
consistency indices values (best fit); C, strict consensus of five fundamental trees obtained when
characters 36 and 46 of Ahlberg and Clack (1998) were ordered, but leaving all characters
unweighted; D, single tree found after reweighting characters by their rescaled consistency indices
values (best fit), with characters 36 and 46 ordered.
