“…According to Harvey et al (1987) and Kelley (1997), differences in life history parameters among taxa evolve in response to variation in mortality patterns, which vary in somewhat predictable ways according to habitat (Ross, 1998). In extant and fossil primates, inferences about life history can be made through the analysis of dental development and tooth eruption sequences, which are correlated to some degree with many life history variables (Anemone et al, 1996;Kelley, 1997Kelley, , 2002Kelley et al, 2001;Schwartz et al, 2002;Kelley and Smith, 2003;Smith et al, 2003). This is particularly useful for fossil taxa, in which the dentition is the primary and most reliable gauge of ontogeny and is more readily preserved in the fossil record (Kuykendall, 1996;Beynon et al, 1998a;Dirks, 2002).…”

“…The age at M1 eruption, as well as rates and durations of tooth development, can be determined from the incremental growth lines found in the enamel and dentine of all teeth. These incremental features include daily cross-striations and striae of Retzius, both of which can be observed in histological sections, as well as perikymata, which are the surface manifestations of Retzius lines (Aiello and Dean, 1990;Hillson, 1996;Kelley, 1997;Dean, 1998;Ramirez Rozzi, 1998;Samonds et al, 1999;Dean, 2000;Schwartz and Dean, 2000;Kelley, 2002). Rates and durations of tooth development, especially age of emergence of M1, correlate well with the chronology of life history events among extant primates.…”

“…Rates and durations of tooth development, especially age of emergence of M1, correlate well with the chronology of life history events among extant primates. These correlations have been applied to fossil (and recently, subfossil) taxa to better understand overall patterns of growth and development and details of the biology of extinct primates (Anemone et al, 1996;Kelley, 1997Kelley, , 2002Kelley et al, 2001;Schwartz et al, 2002;Smith et al, 2003).…”

“…Interestingly, all predictions so far for M1 emergence in fossil apes (Kelley 1997(Kelley , 2002Kelley & Smith 2003;Dean 2006) actually fall below the simulated median age of attainment for M1 emergence predicted in figure 3 as indeed do most estimates for early hominins. This raises questions about how different great ape dental development in the Late Miocene might have been to that known today for modern P. troglodytes and how good a model modern Pan is for comparisons with the earliest hominins.…”

A chronology of dental development in Pan troglodytes is arguably the best available model with which to compare and contrast reconstructed dental chronologies of the earliest fossil hominins. Establishing a time scale for growth is a requirement for being able to make further comparative observations about timing and rate during both dento-skeletal growth and brain growth. The absolute timing of anterior tooth crown and root formation appears not to reflect the period of somatic growth. In contrast, the molar dentition best reflects changes to the total growth period. Earlier initiation of molar mineralization, shorter crown formation times, less root length formed at gingival emergence into functional occlusion are cumulatively expressed as earlier ages at molar eruption. Things that are similar in modern humans and Pan, such as the total length of time taken to form individual teeth, raise expectations that these would also have been the same in fossil hominins. The best evidence there is from the youngest fossil hominin specimens suggests a close resemblance to the model for Pan but also hints that Gorilla may be a better developmental model for some. A mosaic of great ape-like features currently best describes the timing of early hominin dental development.

“…Most species of Miocene apes appear to have enjoyed mostly frugivorous diets similar to those of living apes (Ungar and Kay, 1995). Miocene apes exhibited prolonged life histories (Kelley, 1997(Kelley, , 2002, which are compatible with stable environments with predictable levels of resource productivity (Jablonski et al, 2000).…”

Primates evolved in the tropical forests of the Late Paleocene or Early Eocene. The cognitive, locomotor and life-history characteristics that define primates evolved under the equable and generally non-seasonal conditions that distinguish such forests. All primates since have carried the biological imprint of this original association with tropical forests. In Asia, the persistence of tropical forests in Indonesia from the Eocene onward has permitted tarsiers to endure and evolve, while other Eocene primates became extinct on their home continents. Following a disastrous decline in tropical forest distribution and primate diversity at the Late Eocene/Oligocene boundary, forests and primates rebounded during the Late Oligocene and Miocene. The dominant Old World primates of most of the Neogene were hominoids, which inhabited large tracts of woodlands and forests throughout Africa and Eurasia. These relatively large, frugivorous animals were quadrupedal, but many were capable of undertaking bridging postures that allowed them to stretch between arboreal substrates. Hominoids reached the apex of their evolutionary success in the Middle Miocene, then declined-as a result of the slow disappearance of their forest homes-in the Late Miocene, especially after 10 Ma. The extirpation of apes at this time can be traced to their inability to live in more seasonal and open habitats. Old World monkeys originated in forest biomes, but became the dominant primate of the late Neogene because of their ability to live in environments ranging from closed, non-seasonal rainforests to open savannahs and alpine meadows. This adaptability can be traced to their slightly faster life histories and their ability to thrive on a wide range of both high-and low-quality foods.
