Direct and indirect causality in living systems

Not all cells are equal: each tissue and organ has its own type of cell. Although the nucleus of each cell in a living system has the same genetic information, each one dispenses of the lion's share of that information and only those genes that are necessary for carrying out the function of the particular organ or tissue to which they belong remain active. Despite the fact that in specific scientific fields, such as ecosystem studies, it is possible to measure the relationships between different variables and to compare the various direct and indirect effects they may have on one another, there has been no such development in the wider context of a General Systems Theory. This paper sets out to address the question of cellular change by interpreting processes such as direct and indirect causality, cellular meiosis and mutation of cells.
