The oldest adult hominid skull ever found was unearthed in Georgia at a site called Dmanisi, along with other fossils, and Tabitha M. Powledge weighs the news in her blogs roundup: "The five individuals are very different from one another in shape of cranium and heaviness of features. So different that if they had been found in geographically different locales, they might well be classified as different species – even though present-day people vary just as much."
