A reply to one of my posts:”Dov, you write: Life’s evolution is not random. It is biased, driven by culture.Be sure you understand that Darwin did not say that evolution is random. He said that evolution is not random. It is driven by natural selection.”B. I never wrote anything that Darwin said. Here, again, is what I say and wrote:Culture is the universal driver of genetic evolutionThe major course of natural selection is not via random mutations followed by survival, but via interdependent, interactive and interenhencing selection of biased genes replication routes at their alternative-splicing-steps junctions, effected by the cultural feedback of the third stratum multicells organism or monocells community to their second and prime strata genome-genes organisms.”Dov Henis(Comments From The 22nd Century)http://blog.360.yahoo.com/blog-P81pQcU1dLBbHgtjQjxG_Q–?cq=1Life’s Manifesthttp://www.the-scientist.com/community/posts/list/112.page#578

It does seem like this study is focused on puzzling out how much each factor influences this one developmental path, but I’m not sure how much it can be extended to other animal groups, given the low chromosome number typical of nematodes.
