>This contradicts scientific findings. That's pretty vague. You keep saying that things are "well-established" by science, but don't provide proper citations.

>This contradicts scientific findings. That's pretty vague. You keep saying that things are "well-established" by science, but don't provide proper citations. The literature on Kenyan athletic performance is mostly pretty speculative and inconclusive. The article that you yourself cite in an earlier comment (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4037248/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4037248/) has a very tentative conclusion: "A critical analysis of this unique phenomenon has shown that these athletes do not descend from a single isolated genetic profile.4 The data suggest that the genes most studied and associated with performance in aerobic endurance running (ACE and ACTN3) do not seem to fully explain the success of these athletes. It seems unlikely that Africa is producing unique genotypes that cannot be found in other parts of the world. So far, the evidence shows that the subjects’ phenotype (molded over time by several factors) seems to have greater influence than their genotype in their long-distance running success.4 While recognizing that this field of study is at an early stage of understanding, the available results show that the identified candidate genes for human performance neither determine nor exclude the possibility of athletic success. Although, the right choice of parents can help in the search for athletic success, this is not the deciding factor between success and failure in sport.4"
