Eigens Biogenesis Theory

According to F. Dyson (1985) (see Sect. 8.5), Eigen has stood Oparin s hypothesis (first cells, then enzymes, and finally genes) on its head by reversing this sequence first genes, then enzymes, and finally the cell. Dyson finds the Eigen theory popular for two reasons  

The experiments used RNA as the working material. RNA replication is considered as a fundamental process. 

The elucidation of the DNA double helix showed that genes are structurally more simple than enzymes (i.e., proteins). 

This is assuming that biogenesis went through the following phases  

Eigen s theory concerns itself with phase two, the focal point of the genesis of the replication process. Apart from the first, each phase requires the previous one as its precondition.
