The life histories of early hominins are commonly characterized as being like those of great apes. However, the life histories of the extant great apes differ considerably from one another. Moreover, the extent to which their life histories correlate with the two aspects of morphology used to infer the life histories of fossil species, brain size and dental development, has remained subject to debate. Increased knowledge of great ape life histories and, more recently, dental development —in… Expand

Dental Ontogeny in Pliocene and Early Pleistocene Hominins
Until recently, our understanding of the evolution of human growth and development derived from studies of fossil juveniles that employed extant populations for both age determination and comparison.Expand
Growth, Development, and Life History throughout the Evolution of Homo
TLDR
Evidence of the pace of growth and maturation in fossil australopiths and early members of Homo is detailed to evaluate the merits of each of these scenarios and new data on the relationship between dental development and life history in extant apes are synthesized. Expand
Measures of maturation in early fossil hominins: events at the first transition from australopiths to early Homo
  • M. Dean
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2016
TLDR
There is, however, limited evidence that some early hominins may have attained a greater proportion of their body mass and stature relatively earlier in the growth period than is typical of modern humans today. Expand
A comprehensive survey of Retzius periodicities in fossil hominins and great apes.
TLDR
The results reinforce the idea that Homo sapiens has evolved a life history distinct from other hominins, even from other members of Homo, and suggest that many of these life history differences may be driven by hypothalamic output from the brain. Expand
Brains, teeth and life histories in hominins: a review.
TLDR
It is suggested that extremely slow brain maturation could be a very recent acquisition of the last H. sapiens populations and the review of the literature suggests caution in drawing conclusions about aspects of the life history of the hominins from the information the authors can obtain from dental development in fossil specimens. Expand
Estimating hominid life history: the critical interbirth interval
TLDR
The analysis suggests that the critical inter Birth intervals of australopithecines, early Homo, and Neanderthals are significantly shorter than the observed interbirth intervals of extant great apes. Expand
Dental development in Homo naledi
TLDR
Tooth formation and eruption in two developing dentitions of Homo naledi, a late-surviving, morphologically mosaic hominin species, indicates a recent emergence of the human developmental pattern and investigates the relationship between dental development and other variables associated with life history. Expand
Growth and Investment in Hominin Life History Evolution: Patterns, Processes, and Outcomes
TLDR
Growth and life history characteristics of apes within a general mammalian / primate paradigm is assessed, using time and energy expenditure as 2 fundamentals that covary with infant survival and success probabilities and suggests that these survival probabilities depend on the quality, amount, and timing of parental care allocated to infants. Expand
Ecological and life-history correlates of enamel growth in ruminants (Artiodactyla)
TLDR
The application in two fossil species provides evidence that EFF angle is a reliable proxy of the life history of extinct mammals, and suggests that the two mechanisms of enamel growth might be subject to different selective forces. Expand
Dental development in living and fossil orangutans.
TLDR
Parts of dental development, including cuspal enamel daily secretion rate, long-period line periodicities, cusp-specific molar crown formation times and extension rates, and initiation and completion ages in living and fossil orangutan postcanine teeth are characterized. Expand

Life-history inference is an important aim of paleoprimatology, but life histories cannot be discerned directly from the fossil record. Among extant primates, the timing of many life-historyExpand
Hominin life history: reconstruction and evolution
TLDR
It is found that body mass is the best predictor of great ape life history events, while the body sizes, brain sizes, and dental development of Homo heidelbergensis and Homo neanderthalensis are consistent with a modern human life history but samples are too small to be certain that they have life histories within the modern human range.

Earliest evidence of modern human life history in North African early Homo sapiens
TLDR
An application of x-ray synchrotron microtomography reveals that an early Homo sapiens juvenile from Morocco dated at 160,000 years before present displays an equivalent degree of tooth development to modern European children at the same age. Expand
Dental microstructure and life history in subfossil Malagasy lemurs
TLDR
The results demonstrate that large body size in primates does not preclude exceedingly rapid dental development, and implies a pattern characteristic of Propithecus and other indrids—rapid dental development despite relatively prolonged gestation. Expand
Toward A Life History of the Hominidae
TLDR
It now appears that the australopithecines were a substantially primitive grade of hominid with life histories more like apes than humans. Expand
Dental evidence for ontogenetic differences between modern humans and Neanderthals
TLDR
It is found that most Neanderthal tooth crowns grew more rapidly than modern human teeth, resulting in significantly faster dental maturation, consistent with recent cranial and molecular evidence for subtle developmental differences between Neanderthals and H. sapiens. Expand
Dental development and the evolution of life history in hominidae
TLDR
Three lines of evidence agree that the unique rate and pattern of human life history did not exist at the australopithecine stage of human evolution, and that growth and aging evolved substantially in the Hominidae during the last 2 million years. Expand
Re-evaluation of the age at death of immature fossil hominids
TLDR
It is shown for the first time that Plio-Pleistocene hominids had markedly abbreviated growth periods relative to modern man, similar to those of the modern great apes. Expand
Age at first molar emergence in early Miocene Afropithecus turkanensis and life-history evolution in the Hominoidea.
TLDR
It is inferred that Afropithecus turkanensis had a life history profile broadly like that of Pan, which is additional evidence to that provided by Sivapithecus parvada that the prolonged life histories characteristic of extant apes were achieved early in the evolutionary history of the group.

Dental development in Megaladapis edwardsi (Primates, Lemuriformes): implications for understanding life history variation in subfossil lemurs.
TLDR
Using reconstructions or estimates of adult body mass, brain size, and diet in Megaladapis, as well as the eruption sequence of its permanent teeth, the efficacy of these variables in predicting the absolute pace of dental development in this fossil species is explored. Expand
