Final answer:
Stone tools found at Dmanisi resemble the Oldowan tools from Africa, the oldest known stone tools dating back to 2.5 to 1.5 million years ago, marking an important stage in early human technological development.
Step-by-step explanation:
Researchers have recovered stone tools at Dmanisi that are similar to the Oldowan tools from Africa. The Oldowan tool industry, recognized as the oldest known stone tool industry, dates back to approximately 2.5 to 1.5 million years ago. It was a period during which early hominins such as Homo habilis and Paranthropus boisei likely used these tools for a variety of purposes, including cutting, scraping, and chopping. Oldowan tools are characterized by their crude and simple construction which can make them difficult to identify. Both the significance of these tools and their technology spread show that early human ancestors were capable of creating useful implements to aid in their survival and exhibit the beginnings of technological development across different regions.
