Results from tests to determine strength of phylogenetic signal in major eigenshapes of extant avian furculae.

‘K’ corresponds to strength of phylogenetic signal estimated by Blomberg et al.'s (2003) K statistic, and ‘P’ to associated p-value for significance of phylogenetic signal. ‘Observed’ corresponds to the observed ‘C’ statistic from Abouheif's (1999) TSFI. ‘’ corresponds to method of Pagel (1999).

其中‘K’代表由Blomberg等人（2003）提出的K统计量所估算的系统发育信号（phylogenetic signal）强度，‘P’则对应系统发育信号显著性检验的关联p值。‘Observed’指代Abouheif（1999）提出的TSFI方法下得到的实测‘C’统计量。‘’指代Pagel（1999）所提出的分析方法。
