Fig. 2: Dam’s body size is positively correlated with clutch/litter size and neonate body size in phrynosomatid lizards.

From: Exceptional parallelisms characterize the evolutionary transition to live birth in phrynosomatid lizards

Fig. 2

Influence of dam’s body size on clutch/litter size (a; y = 1.1321x − 1.2362, two-sided P < 0.001, n = 64 oviparous species and 36 viviparous species) and on the body size of neonates (b; y = 0.2893x + 0.9064, two-sided P < 0.001, n = 39 oviparous species and 25 viviparous species). Data are presented as mean values, and regression lines are wrapped by 95% confidence bands. The regression slopes were estimated by phylogenetic regressions (PGLS), and the source data are provided as a Source Data file.
