An interview with Marc Kirschner and John Gerhart


Dear Sirs,

By the term "facilitated variation" it would appear that you are implying a directing force that somehow selects benificial mutations on behalf of the organism. This question is substantiated by your explanation that the direction was already present in the DNA of the animal as "conserved core processes" and acted upon by some "poised response system". I am concerned that "For open-minded doubters of Darwinian evolutionary theory" this explanation of the plausibility of life seems rather childish and would lend creedence to the arguement that the information for life was 'built-in' from the beginning, but is now just being discovered by science to be so.
Who reviews your papers?
