There has always been a microscopic lens on the internal and external similarities between twins, who are “often characterized as being closer than any other human relationship.” “Twins are constantly forced to share, compete, and take each other into consideration in their daily lives,” according to the Twin Research Unit of Finland’s Department of Public Health. The family environment, including sibling relationships, has strong impact on children’s development and behavioral outcomes. At first glance, one couldn’t tell 10-year-old fraternal twins Ella and Rylie Cress apart. A purple pair of glasses worn by Ella is the only noticeable difference between the two girls, on the exterior. Originally from New Marshfield, Ohio, the family lives in a double-wide trailer off of highway 56 with their grandma and mom. Being a twin comes with heightened competition and jealousy between the pair, according to their mother April. It also comes with a bond that is like no other, one that can only be formed through a lifetime of shared experiences. Ella and Rylie share a room that fits two twin sized mattresses, some toys, and a lot of books. Their personalities are “completely different,” yet also “the same,” according the April. This photo essay, Two-Fold: The Anomaly of Twins explores the complex evolution of power dynamics and interpersonal relationships between twins at a formative age.
