Obstetric history documents the reality of multiple births: twins, triplets, and higher-order multiples occur with documented frequency. The biology of triplet birth suggests three individuals sharing womb, nutrients, and developmental space equally. Yet the claim inverts this: of three potential individuals, two were unable to survive the shared space with the third. It's not about developmental capacity but about the incompatibility of certain presences—something about the one prevented the others from achieving independent existence.

A maternal health researcher named Dr. Patricia Wells was examining historical medical records from the 1940s when she noticed an unusual pattern in obstetric notes: scattered references to triplet pregnancies where only singleton delivery occurred, documented with clinical notation but without explanatory comment about the other potential births. Wells theorized that these notations might reference incomplete multiple births, though the medical literature offered no clear category for such occurrences.

The image suggests a kind of intrauterine selection: not competitive in the conventional sense, but rather the presence of one individual creating conditions incompatible with others' survival. It's not pathology or developmental abnormality but rather the simple fact of the one's presence making space for others impossible. It reframes gestation as something other than collaborative process—it becomes a space of incompatibility where certain presences simply cannot coexist.
