Regular siblings share 50 percent of their DNA, but identical twins share much more, though (some say) they may not be genetic equivalents. Historically, people have always found identical twins mysterious. They've constructed elaborate myths about them, depicting them as “halves of the same whole” with special powers, deep connections, and evil tendencies.

This fascination persists today. In his latest series “Twins,” Beijing-based photographer Gao Rongguo took profile pictures of identical twins in their 50s, positioning them so that they appear to be facing one another. The final portraits seem like eerie, warped mirror images. The photo juxtapositions reveal the differences between the pairs, and these differences are mostly (if not completely) explained by the subjects' different life paths and experiences.

“He/she used to have the same face, lived in the same family, but their lives changed due to various reasons after growing up,” Rongguo says. What began as halves of the same whole have evolved into two completely unique human beings, whose own personal choices resulted in the superficial differences.
