• Resumen

  • According to the Digital Arch Model (DAM), all limb bones are derived from a single cell condensation process. First, the condensation of one proximal bone is formed (humerus in the arm, and femur in the leg), which subsequently branches to form two bones (ulna and radius in the arm, and tibia and fibula in the leg). The digits then branch off from the condensation of the ulna or fibula. However, two articles [ 1. , 2. ] have now challenged this model.
