Dmanisi hominin fossils in Georgia: human skeletons



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.

Sister cities discussed: Canberra and Islamabad

Two months ago, in March 2015, Australia and Pakistan agreed to explore ways to deepen ties. The relationship between Australia and Pakistan has been strong for decades, and the two countries continue to keep dialogues open. The annual bilateral discussions were held in Australia in March to continue engagements on a wide range of matters of mutual interest.

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.
