纳米比亚沙漠神秘圆形裸地之谜
Across the barren plains of the Namib Desert in southern Africa, strange circular patches of bare soil dot the landscape. These are known as fairy circles, and they have puzzled scientists and travelers for decades. Each circle is surrounded by a ring of taller grass, creating a perfectly geometric pattern visible even from the air.
For years, researchers have debated what causes these mysterious formations. Some argue that termites are the architects, eating plant roots in a circular pattern underground. Others believe the circles are a result of plants competing for scarce water, with larger plants killing smaller ones in a self-organizing pattern. Both theories have passionate supporters, but neither has been proven conclusively.
