THE MIRACLE OF THE IMMUNE SYSTEM

who once proclaimed the thymus to be a vestigial organ, now advanced a
totally opposite theory for the same organ. They claimed that the thymus
did not exist before, and originated through gradual evolution. They still
maintain that the thymus formed in a longer evolutionary period than
many organs. However, without the thymus, or without its being fully de-
veloped, T cells could not have learned to identify the enemy and the de-
fence system would not have functioned. Someone without such a system
would not survive. Even your reading this sentence now is proof that the
thymus was not created through a long evolutionary process, but has al-
ways existed, perfect and intact in all respects, since the advent of the first
human being.

phocytes produced in the white pulp are first transferred to the red pulp
and then join in the blood stream. A
