Prof Christopher Dean
Christopher Dean is
currently Professor of Anatomy in the Department of Cell and Developmental
His background is in dental surgery, human biology and in human and comparative anatomy. He has published extensively on topics related to his research and co-authored two textbooks An Introduction to Human Evolutionary Anatomy, with Leslie Aiello (1990), and Core Anatomy for Students with John Pegington (1995).
My principal research aim is to determine where, when and why modern humans evolved an extended ~20 year period of growth and development. To research this problem I have pioneered ways of studying incremental markings in fossil primate tooth tissues. Teeth are abundant in the fossil record and contain incremental markings that allow us to retrieve information about the rates of and direction of cell movement during tooth development. Some of the mechanisms of morphological change during human evolution have been described in this way and it has been possible to determine the timing of key events during the period of growth and development in certain fossil primates. This research theme drives an extensive international interdisciplinary research effort with collaborations that draw on clinical science, comparative anatomy and palaeontology.
Recent clinically related studies: A study of enamel growth trajectories in teeth from ovarian teratomas: The timing of linear enamel hypoplastic lesions on anterior tooth crown surfaces in modern populations: Tooth root growth during the supraosseous eruptive phase in children aged 4-7 years.
Recent comparative projects on Miocene fossil primates: Dental development in Anapithecus an extinct primate with a uniquely fast life history profile: Rates of enamel growth in the smallest extinct monkey (Victoriapithecus, ~5kg) and the largest extinct ape (Gigantopithecus ~300kg): Tooth root morphology and dietary adaptation in Gigantopithecus.
Recent comparative projects on Plio-Pleistocene fossil hominids: The life history profile of Homo erectus determined from rates of enamel growth: A histological analysis of Neanderthal enamel and dentine development in fossils from La Chaise-de-Vouthon, Charente, France.
Current ongoing collaborations include: Detecting a weaning signal in archaeological and fossil remains by tracking pre- to postnatal strontium:calcium ratios through enamel using laser ablation plasma mass spectrometry: Comparative studies on rates of odontoblast differentiation along growing tooth roots.
