Our general conclusion is simply stated: many lineages display phyletic size increase; allometric changes almost always accompany increase in body size. We cannot judge adaptation until we separate such changes into those required by increasing size and those serving as special adaptations to changing environments. In our view, the three australopithecines are, in a number of features, scaled variants of the "same" animal. In these characters, A. africanus is no more "advanced" than the larger… 

Fossils and the mosaic nature of human evolution

These new fossils, dates, analyses, and interpretations lead to confirmation and refinement of the mosaic scheme of human evolution as proposed by early evolutionists such as Lamarck, Haeckel, and

Body Size and Skeletal Allometry in African Apes

Morphological analyses of the teeth and locomotor skeletons of pongids and humans also corroborate the Ferris et al. branching sequence, and a variety of shared, unique features of the karyotypes of African apes lend strong credence to this phylogeny.

THE PATTERN OF HUMAN EVOLUTION: Studies on Bipedalism, Mastication, and Encephalization

The recent and sudden proliferation of hominid fossil discoveries sparks new interest in human evolution, especially in the early part of the story. In the last decade the sample of

The Origin of the Genus Homo

The first good evidence of early Homo shows that the first members of the species H. erectus were very like the authors' own species in many respects, including large people with sexual dimorphism in body size to match that of modern human populations, relatively large brains, and had modern limb proportions that show physiological adaptations according to Allen’s rule.

Body mass and encephalization in Pleistocene Homo

It is shown that two independent methods of body-mass estimation yield concordant results when applied to Pleistocene Homo specimens, and on the basis of an analysis of 163 individuals, body mass in Pleistsocene Homo averaged significantly (about 10%) larger than a representative sample of living humans.

Start Small and Live Slow: Encephalization, Body Size, and Life History Strategies in Primate Origins and Evolution

It is argued here that it is an understanding of early primate brain evolution, which primates represent the most diverse mammalian order generally characterized by such high levels of encephalization, which is needed to understand their origins and early evolution.

Hinoid morphology and proportions are seen as having developed from parallel increase in body size and necessarily associated allometry, suggesting that more than one kind of locomotor pattern could have given rise to their distinctive shape.

The results of this study fail to resolve the central question of whether the last common ancestor of the African apes and humans "knuckle-walked" and it is suggested here that this may be an unresolvable problem.

Conservatism and Adaptability during Squirrel Radiation: What Is Mandible Shape Telling Us?

The results found a strong phylogenetic signal in the family as a whole as well as in the main clades, which indicates that ancient adaptations kept a prominent role, with most genera having diverged little from their ancestral clade morphologies.

In reviewing the history of any group of animals one is impressed by the fact that the largest known representatives are usually geologically younger than their smaller relatives, and individual size commonly averages smaller when a group first appears than at any subsequent stage in its history.
