There are lookalikes, and then there’s doppelgängers. It is strangely pleasing when you see your replica — it is like looking into the mirror. However, it is odd when you mistake a stranger’s face for someone you know. Tim, is that you?
“it’s when you see someone and you think it’s the other person. It’s the way of being, the sum of the parts.”
Of course, when you put two lookalikes side by side you start to notice the subtle differences in their hair shape, eyes, mouth, teeth, and nose. Our brains process faces like we do maps.
“the brain employs an area known as the fusiform gyrus to tie all the pieces together. If you compare it to finding a country on a map, this is like checking it has a border with France and a coast.”
Naturally, many people look the same because they share common traits. According to the article, 55% of the world’s population has brown eyes. There’s an abundance of ‘average faces.’
But there’s only so many genes to pass around. So what are the chances your twin is out there amongst 7.4 billion people, waiting to be found? It’s unlikely. The population has to be around 150 million to statistically stand a chance.
“It is entirely possible for two people with similar facial features to have DNA that is no more similar than that of two random people.”
