From page 48 of The Evolution of the Long-Necked Giraffe (Giraffa camelopardalis L.) – What do we really know? (Part 2) by biologist and genetic mutations expert Wolf-Ekkehard Loennig of the Max Planck Institute for Breeding Research:
In the first part of the paper we have come to the conclusion that the assertions on the evolution of the long-necked giraffes by Ulrich Kutschera, Richard Dawkins and Kathleen Hunt do not have a scientific basis. This is also true for macroevolutionary propositions of Mitchell and Skinner and others, which have been discussed in the second part. Although an absolute negative proof is nearly or completely infeasible, nevertheless the scientific data that are available to date on the question of the origin of the giraffe make a gradual development by mutation and selection so extremely improbable that in any other area of life such improbability would force us to look for a feasible alternative.
Yet biologists committed to a materialistic world view will simply not consider an alternative. For them, even the most stringent objections against the synthetic evolutionary theory are nothing but open problems that will be solved entirely within the boundaries of their theory. This is still true even when the trend is clearly running against them, that is, when the problems for the theory become greater and greater with new scientific data. This essential unfalsifiablity, by the way, places today’s evolutionary theory outside of science, one of whose defining characteristics is that theories can only be considered to be scientific if they are falsifiable, and when they set forth criteria by which they can potentially be falsified.
Just food for thought.
