Researchers from the University of the Philippines studied human migration patterns in the Sulu Archipelago by analyzing chicken DNA, with results published in Royal Society Open Science.
Michael James Herrera and his team examined mitochondrial DNA from chickens to understand genetic diversity and migration activities.
The study suggests the Philippines, particularly Luzon, may have been a key origin point for both chickens and human migration in the area.
The findings challenge previous ideas about cultural uniformity across the Philippines.
The research highlights a deep connection between the people of the Sulu Archipelago and chickens, reflected in their culinary practices and rituals.
By using chicken DNA to map ancient routes, the study offers new views on prehistoric and historic human movements.
The researchers stress the role of chickens in tracing human migration in the region.
