Normally evolution does well with certain models along with assumptions (without observational data). But according to a new research paper in nature not even models which hold to certain assumptions confirm evolution!
Four universities conducted research on contemporary human populations in order to discover advantageous mutations, along with the rate of degradation by mutations. Trying to understand diseases from the present is one thing, it’s quite another trying to obtain knowledge of historical evolution which goes by the assumption of many millions of years.
“Analysis of 6,515 exomes reveals the recent origin of most human protein-coding variants…We estimate that approximately 73% of all protein-coding SNVs [single-nucleotide variants] and approximately 86% of SNVs predicted to be deleterious arose in the past 5,000–10,000 years. The average age of deleterious SNVs varied significantly across molecular pathways, and disease genes contained a significantly higher proportion of recently arisen deleterious SNVs than other genes.”
The researchers used the term “explosive population growth” because of its long age assumption whereby, “selection has not had sufficient time to purge them from the population.” Researchers then claim that Europeans had stronger genetic drift, than Africans which is strange because genetic drift doesn’t know the difference. Obviously, they are fudging their assumptions in more ways than one!
They give an assessment of their findings…
“More generally, the recent dramatic increase in human population size, resulting in a deluge of rare functionally important variation, has important implications for understanding and predicting current and future patterns of human disease and evolution.”
“For example, the increased mutational capacity of recent human populations has led to a larger burden of Mendelian disorders, increased the allelic and genetic heterogeneity of traits, and may have created a new repository of recently arisen advantageous alleles that adaptive evolution will act upon in subsequent generations.“
Advantageous mutations? Where are they? The researchers provide no examples in which they observed! They merely assumed it, because it’s part of evolution! This is what you call, “circular reasoning!” If the supposed evolutionary past doesn’t add up with the present data, how is this shed light on future patterns for evolution? When a theory displays a considerable pattern that shows increasing complexity in its explanation, the theory is not valid!
Rather than observing advantageous mutations, they observed a “larger burden of Mendelian disorders” afflicting mankind which is vital for understanding diseases not evolution. The research does however confirm a creation scientist’s (John Sanford) proposal which is known as genetic entropy where the genetic load increases dramatically. That would be a problem for evolution, because that observation makes it impossible for mankind to survive tens of thousands of years!
Here is more on the genome in this interview with John Sanford…
And here is part two of the interview with John Sanford…
The researchers are baffled by their finding as one can read by what they expected in the evolutionary framework verses what they observed!
“The site frequency spectrum (SFS) of protein-coding SNVs revealed an enormous excess of rare variants (Fig. 1a). Indeed, we observed an SNV approximately once every 52 base pairs (bp) and 57 bp in European Americans and African Americans, respectively, whereas in a population without recent explosive growth we would expect the SNVs to occur once every 257 bp and 152 bp in European Americans and African Americans, respectively (Supplementary Information).”
“Thus, the European American and African American samples contain approximately fivefold and threefold increases in SNVs, respectively, attributable to explosive population growth, resulting in a large burden of rare SNVs predicted to have arisen very recently (Fig. 1b).”
“For example, the expected age of derived singletons, which comprise 55.1% of all SNVs, is 1,244 and 2,107 years for the European American and African American samples, respectively. Overall, 73.2% of SNVs (81.4% and 58.7% in European Americans and African Americans, respectively) are predicted to have arisen in the past 5,000 years. SNVs that arose more than 50,000 years ago were observed more frequently in the African American samples (Fig. 1b), which probably reflects stronger genetic drift in European Americans associated with the Out-of-Africa dispersal.”
Their findings conflict with the whole long ages notion which comes from the ‘theory’ of evolution but does shed light on understanding diseases better while containing evidence for a population that has been around for 5,000 to 10,000 years! Which confirms what? Yes! It confirms creationism!
