The Tribe That Sees Like No One Else

Nestled in a grassy valley of north-eastern Namibia, Opuwo may seem like a crumbling relic of colonial history. With a population of just 12,000, the town is so small that it would take less than a minute to drive from the road sign on one side of town to the shanty villages on other. Along the way, you would see a hotchpotch collection of administrative offices, a couple of schools, a hospital and a handful of supermarkets and petrol stations.

For many of the people living in the surrounding valley, however, this small town is also the first taste of modern life. The capital of the Kunene region, Opuwo lies in the heartland of the Himba people, a semi-nomadic people who spend their days herding cattle. Long after many of the world’s other indigenous populations had begun to migrate to cities, the Himba had mostly avoided contact with modern culture, quietly continuing their traditional life. But that is slowly changing, with younger generations feeling the draw of Opuwo, where they will encounter cars, brick buildings, and writing for the first time.

How does the human mind cope with all those novelties and new sensations? By studying people like the Himba, at the start of their journey into modernity, scientists are now hoping to understand the ways that modern life may have altered all of our minds. The results so far are fascinating, documenting a striking change in our visual focus and attention. The Himba people, it seems, don’t see the world like the rest of us.

The first hints that modernisation could change our vision came from the Victorian anthropologist WHR Rivers, who explored the islands of the Torres Strait, between Australia and Papua New Guinea at the turn of the 20th Century. As he met the locals, he offered them various sensory tests, including the following phenomenon, known as the Muller-Lyer illusion.
