The fossilized skeletal remains of Lucy, a 3.18-million-year-old australopithecine and one of the most famous early human ancestors, are being exhibited for the first time in Europe at the National Museum in Prague. Discovered half a century ago in Ethiopia, Lucy's bones rarely leave the country. The exhibition, which opened in late August 2025, offers a unique opportunity for the public to view these ancient fragments outside Ethiopia. Lucy is often referred to as the "grandmother of humanity" and has played a crucial role in advancing scientific understanding of human evolution. Recent studies related to primate evolution, such as the link between longer thumbs and larger brains, continue to shed light on evolutionary developments connected to early human ancestors like Lucy.
