From: Early anthropoid femora reveal divergent adaptive trajectories in catarrhine hind-limb evolution
Shape analysis of the anthropoid proximal femur. The plot shows the first two principal components of an analysis carried out on the between-group covariance matrix (bgPCA). The groups represent extant species and fossil centroids, with individual specimens and fossils plotted post hoc. Thin-plate-spline (TPS) warped versions of DPC 24466 depicting extremes of variation along each axis are represented in Supplementary Fig 4. The colour codes are as follows: New World monkeys, light brown; Old World monkeys, green; great apes and humans, orange; hylobatids, purple; fossil hominins, pink; other fossil primates, grey; the Aegyptopithecus DPC 24466 femur is black. Taxonomic attributions of the fossils represented are: DPC 24466, Aegyptopithecus zeuxis; MACN-A 5758, Homunculus patagonicus; KNM-MB 35518, Victoriapithecus macinnesi; NHMW1970/1397/0023, Epipliopithecus vindobonensis; MUZ-M80, Morotopithecus bishopi; KNM-MW 13142A, Ekembo nyanzae; BMNH-M 16331, Equatorius africanus; IPS41724, cf. Dryopithecus fontani; IPS18800, Hispanopithecus laietanus; AL333-3 and AL288-1, Australopithecus afarensis; SK 82 and SK 97, cf. Paranthropus robustus; KNM-ER 1481, cf. Homo erectus.
