The existence of megaliths along Europe's Atlantic coast from Britain to Spain tells us what about early European societies?

Question

Quizplus · Accepted Answer

The existence of megaliths along Europe's Atlantic coast indicates there was an exchange of both goods and ideas among early European peoples, as the construction of similar structures across a wide area suggests shared knowledge and possibly shared cultural practices. There is no evidence to suggest a single empire controlled the region, that early European peoples had little contact with other lands, or that they shared a single religion.
