Debbie Allen

As I have discovered by examining my past, I started out as a child. Coincidentally, so did my brother. My mother did not put all her eggs in one basket, so to speak: she gave me a younger brother named Russell, who taught me what was meant by 'survival of the fittest.'

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
