why do somalis have lightbulb shaped heads?

The term "lightbulb-shaped head" regarding Somalis is often used to describe a characteristic head shape observed in some individuals from the Horn of Africa, particularly among Somali people. This shape can be largely attributed to genetic and environmental factors, including dietary influences and traditional practices. It's important to approach discussions about physical characteristics with cultural sensitivity and an understanding of the diversity within any ethnic group. There is a wide range of variations in head shapes and sizes across populations, and attributing specific traits to particular ethnicities can sometimes perpetuate stereotypes. If you're interested in the subject from a scientific or anthropological perspective, the head shape may reflect adaptations to environmental conditions, cultural practices, or genetic inheritance, but it should always be discussed respectfully and without generalization.
