Box plots of residual elongation. We plot species mean values for residual elongation in the all primate line (Residual A from Table 1). The distribution of values within clades corresponds very effectively to degree of agility of locomotion. For fossils the variation corresponds with locomotor agility hypotheses primarily based on more skeletal functions [30]. When these residual information sets are examined with phylogenetic ANOVA, a powerful connection in between elongation and behavior is revealed (Table 7) which means that calcaneal elongation is broadly related to behavior in ` ` contrast towards the conclusion of Moya-Sola et al. [7]. See prior figures for taxon abbreviations. doi:ten.1371/journal.pone.0067792.gslow-climbing, and/or terrestrialism within the indrioid clade. In the event the ancestral indriid was a slow climber and/or terrestrial and had calcanei with really low elongation ratios [certainly a possibility provided that such a situation exists in specific subfossil species (Table 2)], then all extant indriids might certainly have seasoned increases in elongation that can't be explained by allometry and reflect enhanced leaping in comparison to their ancestors. Whilst such alterations can only be appreciated with analyses that extensively sample subfossil lemur morphology, the restricted subfossil information in our study show that residual elongation in extant indriids is higher than that in Archaeolemur, Paleopropithecus, and Mesopithecus, which are reconstructed as semi-terrestrial, antipronograde, and slow-climbing, respectively [100] (see Fig. 11). Whilst Babakotia basically has higher residual calcaneal elongation, as stated within the approaches, we don't have certain predictions for the elongation constraints of inverted quadrupeds, and/or extremely specialized, sloth-like quadrumanous suspensory taxa. It may be that quadrumanous suspension permits and/or selects for higher elongation than is possible/useful for pronograde and orthograde animals of comparable size in some circumstances. The truth that Cynocephalus volans has the greatest degree of elongation amongst non-primate euarchontans, regardless of also becoming by far the most huge in this group, may perhaps reflect a equivalent functional correlation. Comparison of elongation in sloths to that of other xenarthrans could supply information to test this thought.

A debated hypothesis that, if true, would add plausibility to this thought is the fact that Mesopropithecus, judged to become anti-pronograde on account of an intermembral index greater than one hundred [100], could be the sister taxon to extant Propithecus [101] (and most likely Avahi at the same time). If an independent behavioral transition to leaping happened extremely recently in Avahi and Propithecus, in comparison to Indri [66], then some elements with the skeleton may still be ``adapting in those taxa. A further more lately posited hypothesis primarily based on molecular data areas the Paleopropithecidae as a sister group of indriids, and areas archaeolemurids as sister of those two clades [66]. Irrespective of when or how lots of occasions leaping evolved in extant indriids, this suggests a lengthy evolutionary history of non-leaping,PLOS A single | www.plosone.orgCalcaneal Elongation in PrimatesFigure 11.
