Figure 4 in Mosaic patterns of homoplasy accompany the parallel evolution of suspensory adaptations in the forelimb of tree sloths (Folivora: Xenarthra)
Figure 4. Geometric morphometric principal components analysis of the ulna, humerus and scapula of xenarthrans. A, the first two axes of the ulna GM analysis. No other principal components (PC) axis accounts for more than 5% of variation. B, the first two axes of the humerus GM analysis. The small amount of variation accounted for by PC2 is likely due to the small sample sizes for the taxa it differentiates, specifically armadillos, the two giant ground sloths, and to a lesser extent Hapalops. PC3 accounts for 5.6% of variation and differentiates Cyclopes from Paramylodon and Glossotherium. No other axes account for more than 5% of variation. C, the first two PCs of the scapula GM analysis. PCs 3 and 4 account for 8.6% and 6.3% of variation, respectively. PC 3 separates Cyclopes from other taxa, and PC 4 separates Cyclopes and Dasypus from Choloepus. No other PC accounts for more than 5% of variation. Sloth scapula specimens identified with a thick rimmed circle and black dot indicate the specimens shown in 4D. D, Choloepus (centre) has a relatively conserved gross scapular morphology (compare with Paramylodon on right), especially when compared with Bradypus (left), but it has mapped functional traits such as an angled scapular spine onto that conserved bauplan. Squares indicate armadillos, rounded squares indicate anteaters, and circles indicate sloths.
Figure 5 in Mosaic patterns of homoplasy accompany the parallel evolution of suspensory adaptations in the forelimb of tree sloths (Folivora: Xenarthra)
Figure 5. Geometric morphometric phylomorphospace of the ulna, humerus and scapula. A, phylomorphospace of the ulna shows that tree sloths inhabit the same region of morphospace, suggesting extensive parallel evolution relative to their last common ancestor, while giant ground sloths and armadillos diverged in the opposite direction and anteaters appear to have diverged little from the last
Figure 1 in Mosaic patterns of homoplasy accompany the parallel evolution of suspensory adaptations in the forelimb of tree sloths (Folivora: Xenarthra)
Figure 1. Phylogeny used in this study showing the relationships among living xenarthrans and extinct sloths based on recent molecular studies (see methods for details on how the tree was constructed). Extant tree sloths are labelled in purple. Hapalops and Acratocnus have been argued to show adaptations for arboreality, although these adaptations might also reflect digging habits. Other sloths are almost certainly terrestrial based on size. None of these forms show adaptation to suspensory behaviours and thus it is likely that this morphobehavioural suite evolved independently in living sloths. A cross symbol (†) indicates an extinct taxon.
