New Findings Confirm Darwin's Theory: Evolution Not Random

New Findings Confirm Darwin's Theory: Evolution Not Random: "When the researchers measured changes in 40 defined characteristics of the nematodes’ sexual organs (including cell division patterns and the formation of specific cells), they found that most were uniform in direction, with the main mechanism for the development favoring a natural selection of successful traits, the researchers said.

'Since random development would not create such unifying trends, we concluded that the observed development was deterministic, not random,' said Professor Benjamin Podbilewicz from the Technion Faculty of Biology."

This article seems hard to validate not having seen the whole article.

The idea of random mutation naturally leads to the conclusions that there should be an uniform chance of productive and non-productive change as a species evolves. 50% have shorter tentacles (positive) and 50% have longer tentacles per generation (negative). The productive change is selected for and the non-productive change is selected against. However, if the genetic offspring show that productive change is more common than non-productive change (70% have longer tentacles and 30% have shorter tentacles before natural selection has a chance to act), then that suggests a mechanism or selection criteria is working much before natural selection.
