One variable that is unaccounted for in my mathematical proof of the impossibility of evolution by natural selection is the way in which close genetic relations are observed to reduce life expectancies rather than enhance them. And yet, it significantly strengthens my argument.
A 2013 study in the Lancet reported that when first cousins reproduce, the baby’s risk of congenital problems such as heart and lung defects, cleft palettes, and extra fingers doubles. The childhood death rate among children of first-cousin marriages was roughly 5 percent higher than the rate in nonrelated marriages.
A 2014 study published in PLOS One found that children of two cousins are likely to have lower IQs and higher rates of mental retardation.
A 1993 study by genetics expert Dr. Alan H. Bittles of the University of London found that childhood death rates were about 16 percent in offspring of marriages of unrelated people, compared with about 21 percent in marriages between cousins.
The significance of this factor is that if a theoretically-advantageous mutation takes place, then the mutated specimens must breed with other identically-mutated specimens in order for the mutation to eventually become fixed. In other words, the children and cousins of the original mutated specimen must interbreed, and have such an advantage over non-mutated specimens that the intrinsic disadvantages of inbreeding are overcome to such an extent as to fix the mutation across the entire population.
However, it is observed that closely-related specimens have a significant built-in DISADVANTAGE with regards to attributes and life expectancies, and therefore, presumably, fitness as well. It would be very useful to learn the average extent to which inbreeding conveys a disadvantage with regards to fertility, as that alone might be sufficient to statistically falsify neo-Darwinian theory.
Given the numerous observed disadvantages of genetic inbreeding, it is very highly improbable that whatever advantage is conveyed by any one mutation will overcome the inherent disadvantages conveyed with it. Which provides further evidence that the theory of evolution by natural selection is not only false, but is obviously absurd.
UPDATE: The rhetorical version.
