THE following outline of the evolution of the pelvis is a by-product of the labors of many paleontologists on the phylogeny and classification of the vertebrates, and of anatomists and anthropologists on the morphology of the pelvis. For convenience and brevity the story is told in the order of evolution and not in the confused order of the historical development of the problem. That the paired fins, including the pectoral and pelvic girdles of the earliest vertebrates, were originally of the… 
Characters Common to Higher Primates and Characters Specific for Man (Continued)
TLDR
The direct relation between the height of the ilium and that of the trunk demonstrates conclusively that man is characterized among all the primates studied by the shortest ilium not only in connection to the ischium, but also in relation to the trunk.
The Homology of the Pelvic Elements of Zygaspis quadrifrons (Squamata: Amphisbaenia)
TLDR
An osteological landmark (acetabulum) not previously detected in this taxon is reported, the presence of which has repercussions that call for a reconsideration of the primary homology hypothesis for the identity of these bones in amphisbaenians and other squamates.

TLDR
It appears from the hominid fossil record of pelvic bones that two periods of stasis exist and are separated by a period of very rapid evolution corresponding to the emergence of the genus Homo, which could be true for the split between African ape and hominids lineages at the end of the Miocene.
Pelvic function in anuran jumping: Interspecific differences in the kinematics and motor control of the iliosacral articulation during take‐off and landing
TLDR
The novel function of the rod‐like pelvis may be to increase the rate of trunk elevation relative to faster rates of energy release from the hindlimbs enabling them to jump farther.
Variation in mouse pelvic morphology maps to locations enriched in Sox9 Class II and Pitx1 regulatory features.
TLDR
The results suggest that genotypic variation is channeled through a subset of developmental processes involved in the generation of phenotypesic variation in the pelvis, and indicates that the evolvability of complex traits may be subject to biases not evident from patterns of covariance among morphological features or developmental patterning when either is considered in isolation.
