 Orangutans also differ from African apes in their more highly arboreal lifestyle, a trait generally viewed as ancestral among the apes.Given that the deepest phylogenetic split in a group is likely to have occurred early in its history, identification of the most basal subclade(s) in a widely dispersed taxon or clade can provide valuable insight into its region of origin.In some situations where it might not otherwise be obvious, the direction of migration away from the area of origin can also be inferred (as in the "Amaurobioides" and Noctilionoidea cases below).
