ABSTRACT
This paper reviewed the development of biological holography theory， discussed on the limitations of biological holography law， and explained the theoretical connotation and basis of the “three-level two-node and three-segment holographic theory” innovatively proposed by Academician TONG Xiaolin， aiming at inspiring new thinking on the theoretical research of biological holography. By observing the human body structure， Academician TONG Xiaolin finds that there is a similar law in the head， trunk， limbs， and fingers （toes） that there are two moveable joints （groups） dividing the part into three segments， and each segment contains all the information of the whole part， which is a holographic phenomenon. Accordingly， Academician TONG creatively put forward the “three-level two-node and three-segment holographic theory” of the human body， and “three levels” respectively refer to the original level trunk， the branch level limbs， and the end level extremities. The “two nodes” refer to the two joints （groups） of each level， and “two nodes” can be further divided into “three segments”. Therefore， there are “two nodes” and “three segments” in each level with a similar distribution pattern， which reflects the holographic distribution law that the part reflects the whole and the whole includes the part.
