Genetic instructions for developing limbs and digits were present in primitive fish millions of years before their descendants first crawled on to land, researchers have discovered. Genetic switches control the timing and location of gene activity. When a particular switch taken from fish DNA is placed into mouse embryos, the segment can activate genes in the developing limb region of embryos, University of Chicago researchers report in Proceedings of the National Academy of Sciences. The successful swap suggests that the recipe for limb development is conserved in species separated by 400 million years of evolution.

As that story in ScienceDaily shows, the long-term intelligent processing of biodevelopment had begun 400 million years before Darwin-worshippers could even dream up the slightest excuse for what they like to call 'evolutionary pressure.' The switches for limbs and digits, which fish do not need, do not want, and cannot benefit from, were starting to be formed. Biodevelopment's intelligent processing was beginning to work out a higher form of animal.
