At the bottom of the Mediterranean Sea, archaeologists uncovered a 10,000-year-old man-made monolith that they believe is evidence of a prehistoric civilization. The rock monument's colossal size (12 meters, or about 39 feet in height) suggests that quite a few people would have been needed to move it — something that would have been difficult if, as previously suspected, the inhabitants had been hunter-gatherers living relatively solitary lifestyles.
The find, which is actually the second of its type, has led archaeologists to suspect that civilization may have "already been shifting towards our modern way of life" earlier than previously thought, according to Evoanth. Together, the two monoliths (the other one was found in the Middle East) suggest that different groups in different parts of the world were beginning to develop a modern way of life simultaneously.
"What was it that was driving so many people, so far apart in the same direction?" asks Evoanth. We can't be sure, but it seems the scientists are one step closer to finding out.
