Common Design

The core question,
Does the similarity in traits characteristics show “transition”…
…or does it show the trademarks of one common designer?*
You are Dave Scott and I claim my £5!!
Firstly, what is ‘common design’? The answer is that it is the capitulation of the intelligent design movement to the empirical evidence of evolution at a morphological, paleontological, geophysical, molecular-biological and cladistical level (excuse my hashed english).
Simply if evolutionary theory is true then there is only one way it can look. You cannot have bats with keratin beaks, you cannot have birds with nippes. Those features appeared after diversification from the last common ancestor. Never, ever, ever, in all the animal and plant species described has this been found to be false. So far 1.7 million species have been described and all hold to this rule.
Design theory is somewhat different, Any feature can be designed in without any intermediate form being needed. You can design a computer with an oil cooling system, a fan cooling system, or a liquid nitrogen cooling system. The cooling systems are lifted directly from completly unrelated technological systems. The new iMac has just got dual core intel processors as opposed to G5 systems. The leap is not possible in the evolutionary paradigm. The mix is only possible through the design paradigm.
So what does common design show us? It shows us that the intelligent design proponents have accepted that the tree of life is exactly described by the evolutionary pradigm, and does not demonstrate the mx and match of features that 1.7 individually designed ‘types’ or ‘kind’ would be expected to show.
Common design also flies in the face of everything we know about design. Whan a design flaw is discovered it is rectified if resources are available. The common design paradigm has theological implications (commonly explained away with arguments about not knowing anything about the mind of the designer) regarding the resources of the creator, his concern for poor design, his intelligence (some of the designs are just dumb), and the existance of sub-optimal design.
Designers fix the problems with their designs. We dont see that.
Oh, and given the tension between prey and predetor, parasite and host, disease and carrier we can go towards multiple designer theory.
