How does a single cell build a 170 billion-cell brain? Scientists discover the astonishing blueprint behind how the human brain builds itself

Scientists have uncovered a surprising principle behind the brain's intricate development from a single cell. Researchers propose that cells, much like spreading human populations, tend to stay near their 'ancestors.' This lineage-based organization, working alongside chemical signals, helps billions of brain cells find their correct positions. This groundbreaking insight could impact fields from biology to artificial intelligence and deepen our understanding of intelligence itself.
