Table 4. Estimates of the phylogenetic signal for each variable using Pagel's Lambda.

Variables	λ (Phylogeny A)	λ (Phylogeny B)
Eye diameter	0.94^{<0.001, <0.001}	0.75^{0.02, <0.001}
Lens diameter	0.95^{<0.001, <0.001}	0.79^{0.02, <0.001}
Standard length	<0.001^{1.0, <0.001}	<0.001^{1.0, <0.001}
Residuals (eye/SL)	0.96^{<0.001, <0.001}	0.94^{<0.001, <0.001}
Dn/Vn organs	1^{<0.001, 1.0}	1^<0.001,1.0
Caudal luminous organs	1^{<0.001, 1.0}	1^<0.001,1.0
Luminous patches	0.99^{<0.001, <0.001}	0.99^{<0.001, <0.001}
Luminous tissue sexual dimorphism	0.93^{<0.001, <0.001}	0.97^{<0.001, <0.001}
Day depth	<0.001^{1.0, 0.04}	0.79^{0.113, <0.001}
Night depth	0.75^{<0.001, <0.001}	0.67^{<0.001, <0.001}

The results are presented for one of the ten randomly selected polytomy resolved phylogenies for the two different phylogenies. A λ value of 1 indicates that the trait gradually accumulates changes over time in a Brownian motion process. A λ values of 0 indicates that no phylogenetic signal is present and that traits have evolved in response to selective processes. The superscript values are likelihood ratio tests different from 0 and 1. Sample size is 61 for all variables except day depth (58).
