What change resulted in the building of European metaliths?

The building of European metaliths, such as menhirs and dolmens, resulted from significant societal changes during the Neolithic period, particularly the shift from nomadic hunter-gatherer lifestyles to settled agricultural communities. This transition led to increased social organization and the establishment of communal rituals, prompting the construction of monumental stone structures. These metaliths served both practical purposes, such as marking territory and burial sites, and symbolic roles in religious and cultural practices.
