Why were the Dmanisi remains important quizlet?
The site of Dmanisi, in the Republic of Georgia, is important because the hominid fossils found there are the youngest of all H erectus finds, dating to 200,000 y.a. 8.
Which hominin species has been found at Dmanisi in the Republic of Georgia?
Early human (or hominin) fossils, originally named Homo georgicus and now considered Homo erectus georgicus, were found at Dmanisi between 1991 and 2005. At 1.8 million years old, they are now believed to be a subspecies of Homo erectus and not a separate species of Homo.
When the 1.9 million year old fossil hominins from Dmanisi Georgia were discovered what was so surprising about them?
But as the bones and tools from Dmanisi accumulate, a different picture of the earliest migrants is emerging. By now, the fossils have made it clear that these pioneers were startlingly primitive, with small bodies about 1.5 meters tall, simple tools, and brains one-third to one-half the size of modern humans’.
Why was the Levallois technique an important innovation?

Why was the discovery of the Dmanisi hominins so troubling for anthropologists?
However, the Dmanisi hominins contradicted these assumptions: they were physically small, and had small brains. Also, these pioneers were armed with primitive stone tools, and thus did not possess the well-developed tool-making techniques researchers had expected.
