Evolution:Pre-Cambrian gene explosion (Introduction)
This article describes a scientific study of Archaean genetic explosion by studying current DNA and extrapolating into the deep past. This provided a base of development for the Cambrian Explosion, but there is no explanation of the driving force behind such a gene expansion other than the apperance of more oxygen in the atmosphere as a correlation. Nor is there an explanation of why those genes were suddenly put to work and used. In studying history one can tell when certain events happened, but not the 'why'.
