A topic of family debate: Who has the fullerface? Ramon says it's Eurides. Today at age 34, the twins are next-door neighbors in Florida, living in identical custom-built houses.

Marta depicts finely detailed faces, while Emma prefers more expansive images: the sky, the rain, objects in motion. They both like to draw as well but have a different approach to their art. Marta (top) Emma (bottom) ? The 15-year-old sisters want to go to the same university and become opera singers. According to a recent field called epigenetics, there is a third factor also in play, one that in some cases serves as a bridge between the environment and our genes, and in others operates on its own to shape who we are. … twin studies have helped lead scientists to a radical, almost heretical new conclusion: that nature and nurture are not the only elemental forces at work.

The following excerpt comes from the January issue of National Geographic:

Schoeller, whose celebrity portraits have graced the covers of more than 20 magazines, took on the subject of identical twins, capturing the subtle differences (or similarities?) between them.
