Question

which striking resemblance between the remains of structures are found in two places​

Answer 1

Answer:

All of them, seemingly independently, struck upon the idea of erecting massive stone structures during the same era in history. These monuments—yes, these are the earliest surviving man-made monuments we know of—are called megaliths, derived from the Latin mega (large) and lith (stone).

Megaliths were constructed either as burial sites or commemorative (non-sepulchral) memorials. The former are sites with actual burial remains, such as dolmenoid cists (box-shaped stone burial chambers), cairn circles (stone circles with defined peripheries) and capstones (distinctive mushroom-shaped burial chambers found mainly in Kerala). The urn or the sarcophagus containing the mortal remains was usually made of terracotta. Non-sepulchral megaliths include memorial sites such as menhirs. (The line separating the two is a bit blurry, since remains have been discovered underneath otherwise non-sepulchral sites, and vice versa.)
