>>21067422The concept of "hybrid vigor" in humans, often referred to as heterosis, is a controversial and misunderstood topic. While some studies suggest that genetic diversity can have certain health benefits, the claims you mention are not conclusively proven and should be viewed with skepticism.Cancer rates: There is no clear evidence that race mixing directly influences cancer rates. Cancer risk is influenced by a complex interplay of genetic, environmental, and lifestyle factors.Autoimmune diseases: Some studies suggest that populations with higher genetic diversity may have lower rates of certain autoimmune diseases. However, this relationship is not well-established and varies by specific condition.Physical abilities: Athletic performance is influenced by a wide range of genetic and environmental factors, not just ancestry. There is no evidence that race mixing inherently improves physical
abilities.IQ and neuron counts: IQ is a controversial and imperfect measure of intelligence, which is influenced by both genetic and environmental factors. There is no scientific basis for the claim that race mixing increases neuron counts or IQ scores.Life expectancy: Life expectancy is determined by a complex interplay of genetic, environmental, social, and economic factors. While some studies suggest that certain admixed populations may have higher life expectancies, this relationship is not well-established and varies by specific
population.In summary, while genetic diversity may have some health benefits, the specific claims you mention are not conclusively supported by scientific evidence and should be approached with caution. The relationship between ancestry, genetics, and health outcomes is complex and not fully understood.
