[ExI] Evolutiion is not random,...

[giovanni santost]

Evolution is a complex phenomenon, of course, a single study, on a very particular, very specific case of a instance of this process cannot be easily generalized to make broad statements on the "underlying process" but still this is a little bit more evidence that indicates that randomness is not an "answer all" to understand Evolution.
  I think this study is very relevant to the kind of discussion we had some time ago on same topic.

  It is claimed that underlying process of evolution is not randomness but instead deterministic processes.


The actual study made no such claims, they said that developmental evolution in the nematode vulva occurred  primarily through deterministic mechanisms.  

Basically, it was a claim that when ways to form a single, already defined structure are evolving, only two of forty factors were random, while the others were at least somewhat convergent.  

See: http://www.current-biology.com/content/article/fulltext?uid=PIIS0960982207021938

All this has no bearing I am aware of on the "underlying process of evolution", which is neither inherently random nor inherently deterministic.
