Researchers have unveiled two "hyperrealistic" reconstructions of adult sisters who lived and worked in a brutal mining community in what is now the Czech Republic more than 6,000 years ago.
The stunning, 3D reconstructions are based on a new analysis of the sisters' remains, which were unearthed more than 15 years ago from a prehistoric chert mine in the South Moravian region. New evidence suggests the sisters worked in the mine, extracting heavy rocks for tools and weapons.
