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.
A phylogeny of Antirrhinum reveals parallel evolution of alpine morphology
<p>• Parallel evolution of similar morphologies in closely related lineages provides insight into the repeatability and predictability of evolution. In the genus <i>Antirrhinum</i> (snapdragons), as in other plants, a suite of morphological characters are associated with adaptation to alpine environments.</p> <p>• We test for parallel trait evolution in <i>Antirrhinum</i> by investigating phylogenetic relationships using Restriction-site associated DNA (RAD) sequencing. We then associate phenotypic information to our phylogeny to reconstruct patterns of morphological evolution and relate this to evidence for hybridization between emergent lineages.</p> <p>• Phylogenetic analyses show that the alpine character syndrome is present in multiple groups, suggesting that <i>Antirrhinum </i>has repeatedly colonised alpine habitats. Dispersal to novel environments happened in the presence of intraspecific and interspecific gene flow.</p> <p>• We find support for a model of parallel evolution in <i>Antirrhinum</i>. Hybridisation in natural populations, and a complex genetic architecture underlying the alpine morphology syndrome, support an important role of natural selection in maintaining species divergence in the face of gene flow.</p>
