Department of Human Anatomy and Cell Biology, Hominid Palaeontology Research Group, The University of Liverpool, Liverpool L69 3GE, England
Ann Anat 186:413-6. 2004..Finally, the findings highlight the importance of employing species-specific correction factors for the calculation of prism length (i.e., life-span of the ameloblast) for life history enquiry...
- Effects of loading on the biomechanical [correction of biochemical] behavior of molars of Homo, Pan, and PongoG A Macho
Department of Human Anatomy and Cell Biology, University of Liverpool, UK
Am J Phys Anthropol 109:211-27. 1999..Overall, Pan appeared to be most generalized, while Homo and Pongo showed a number of unique specializations, which are in accordance with what is currently understood about their respective masticatory apparatus and dietary niche...

Hominid Palaeontology Research Group, Department of Human Anatomy and Cell Biology, University of Liverpool, Liverpool L69 3GE, UK
Am J Phys Anthropol 126:427-34. 2005..Such findings appear to be supported by archeological evidence...
- Did knuckle walking evolve twice?M Dainton
Department of Human Anatomy and Cell Biology, The University of Liverpool, UK
J Hum Evol 36:171-94. 1999..In light of morphological, behavioural and ecological data currently available it is parsimonious to suggest that knuckle walking has evolved in parallel in the two lineages...
- Dietary adaptations of South African australopiths: inference from enamel prism attitudeGabriele A Macho
Department of Archaeological Science, University of Bradford, Bradford BD7 1DP, England, UK
J Hum Evol 57:241-7. 2009..africanus are better adapted to cope with more laterally-directed loads (Phase II) commonly associated with roll-crush and mastication. Overall, teeth of P. robustus appear stiffer, while those of A. africanus seem more wear resistant...

- Functional significance of the microstructural detail of the primate dentino-enamel junction: a possible example of exaptationDaisuke Shimizu
Palaeoanthropology Research Group, Centre for Research in Evolutionary Anthropology, School of Human and Life Sciences, Roehampton University, London SW15 4JD, UK
J Hum Evol 52:103-11. 2007..However, given the equivocal relationship between scallops and presumed bite force across mammalian taxa, we propose that scallops could in fact be exaptations...

Archaeological Sciences, Division of Archaeological, Geographical and Environmental Sciences, School of Life Sciences, University of Bradford, Bradford, England
Anat Rec (Hoboken) 291:175-82. 2008..For (palaeo)biological applications, the findings suggest that the absolute strength of teeth (e.g., bite force) cannot be predicted with certainty, whereas kinematic parameters of the masticatory apparatus can...
