Biological complexity: cell division requires being loose (Introduction)

The evolving cell must loosen itself from others:

"Researchers found that CDK1, the master regulator of the cell cycle binds directly to, and modifies, the core protein talin that is essential to the process of cell adhesion. This interaction represents a coupling of the cell proliferation and adhesion processes. This indicates a unifying mechanism by which the processes of cell division and adhesion are controlled.

"Dr Ben Goult, Reader in Biochemistry at the University of Kent and a Principal Investigator of the paper said: 'The potential of this discovery is huge as it provides a new understanding of how cell division is coordinated within the confines of a complex multicellular organism. Cell division needs to be tightly coupled to the cell adhesion to allow our cells to divide without disrupting the integrity of our tissues and organs. This research is vital in our understanding of other cellular diseases and of cancer's ability to spread within the human body.'"

Comment: another example of irreducible complexity. All of this mechanism must have all parts in place all at once to work. It must become loose to start cell division process. Only design fits.
