Who is entitled to social welfare?

A Danish researcher found that a universal psychological instinct triggers decisions on deservingness of welfare recipients, regardless of cultural differences. This instinct dates back to the Stone Age, when sharing food was crucial for survival, and influences modern attitudes towards help and support.

Later Stone Age got earlier start in South Africa than thought

A recent study has pushed back the estimated emergence of the Later Stone Age in South Africa to approximately 44,000 to 42,000 years ago. This finding suggests that early humans inhabited the region during this time period, coinciding with the migration of modern humans from Africa to Europe around 45,000 years ago.

Research finds Stonehenge was monument marking unification of Britain

The study reveals that Stonehenge was built as a monument to unify the peoples of Britain after a long period of conflict between eastern and western regions. The monument's alignment suggests it was more significant during winter solstice than summer solstice, with evidence pointing to a unified cultural shift around 3,000 BC.

Genes shed light on spread of agriculture in Stone Age Europe

The study found that genetic variation of today's Europeans was strongly affected by immigrant Stone Age farmers, but hunter-gatherer genes still remain. The agricultural revolution is believed to have been driven by people migrating from Southern Europe, who lived alongside hunter-gatherers for thousands of years before interbreeding.

Face-to-face with an ancient human

A reconstruction based on the skull of Norway's best-preserved Stone Age skeleton, Viste Boy, has been scientifically rebuilt to study features of a boy who lived outside Stavanger 7,500 years ago. The model reveals a strong and muscular individual with scaphocephaly, challenging earlier theories about his health.

Passage graves from an astronomical perspective

Researchers found that passage graves in Denmark are oriented towards the full moon and lunar eclipses, hinting at an ancient astronomical calendar. The study suggests that the Stone Age people may have used these alignments for ritual practices and predicting lunar eclipses.

World's oldest ritual discovered

Researchers uncover evidence of advanced rituals performed by modern humans in Africa for 70,000 years, featuring a python rock with man-made indentations and no signs of normal habitation.
