Introduction
In this paper, I intend to outline the process of sperm maturation in the epididymis of the common brushtail possum Trichosurus vulpecula, and I hope to show how a study of this process may help to illuminate the selection pressures behind the evolution of the male tract in modern eutherian mammals, as well as in the marsupials.
