At the Georgian National Museum in Tbilisi is an
exhibit of the Dmanisi hominin (human) fossils. Dmanisi is a region in southern
Georgia, and is the most productive early paleolithic archeological site in the
world. To date it has produced five individual human skeletons from over 60
cranial (skull) and post-cranial remains. The five individuals are sub-adult,
adult, and an older adult.
The Dmanisi hominin fossils share similar
morphological traits with early human fossils from Africa, such as the more
forward projecting face and U-shaped jaw. The Dmanisi hominin fossils were
fully bipedal (standing on two legs).
One of the Dmanisi hominin fossils is a toothless
skull and mandible of an old adult. It is thought that he or she lived for
several years without teeth before the person died. The person could only eat food that
did not require heavy chewing. This edentulous person raises interesting
questions about social structures, such as whether the person relied on others in the
community for procuring or processing food, or whether he/she only ate soft plants
or animal parts. It is the earliest known specimen of a severe masticatory
(chewing) impairment in hominin fossil records.
The Dmanisi human fossils date back to about 1.8
million years, and are dubbed Homo
Georgicus.
