"Growth and development in Plio-Pleistocene hominids"
During my visit to Max Planck Institute for Evolutionary Anthropology, Department of Human Evolution, one short meeting was settled to start a new
project, "Growth and development in Plio-Pleistocene hominids". It deals with issues of evolution of human-like growth and developmental
patterns. The project team consists of four separate groups each of which
has a concrete objective. One is for study on cranial development. It focuses on the brain growth and the estimation of age at death for the
fossil hominids. It interests the first appearance of secondary
altriciality. The second is based on the dental microstructure. It includes the perikymata increment on the enamel surface and also the
observation of thin cross-sections. The third is on the postcranial bones,
which is almost untouched part in the whole skeletal remains. It focuses on the body proportion and the robusticity. The fourth
concerns the development of the genus Australopithecus. These four groups cooperate
with each other and develop their own discussions into wider points of view.
The second day held my talk on "Postcranial growth and development of the
Dederiyeh Neandertal children". It announced the contribution of the Japanese team in exploitation of Paleoanthropology in the Levant,
especially for the excavation of the team Dederiyeh in Syria, and introduced my study of the postcranial growth on the Dederiyeh
children. After several questions and comments, further prospects were discussed.
