Environmental stress can change a family’s genetic makeup
Being subjected to endless warfare and/or the Trail of Tears altered the genetic makeup of Native Americans.
One of the most astonishing discoveries made in 2017 and early 2018 was that environmental conditions or extreme emotional stress can almost instantaneously change the genetic functions of human beings. On the other hand, walking an hour a day increases your IQ and generally prevents the onset of senility in the elderly. Regular, moderate exercise changes the genetic sequencing of humans to make them more resistant to disease. Such traumas as wars, persecution, divorces and violent deaths of loved ones can make one extremely inclined toward cancer and degenerative diseases. What’s even more astonishing is that these genetic changes are passed on to your children. These discoveries totally debunk the long held belief among scientists that evolutionary changes always occurred in humans, unnoticed, over eons of time.
Astronaut Scott Kelly spent a year in space. After his return to earth, his body was thoroughly examined by medical scientists then compared to his identical twin, Mark Kelly, who was also an astronaut. In March 2018, it was announced that there was a 17% change in his genetic sequencing, when he returned to Earth and even a year later, there was a 7% change in his sequencing. Some media outlets attempted to garner readership by saying that there was a 7% change in his genetic makeup. That is not the same thing. Human genes only differ from apes by 2%. Genetic mutations don’t occur that fast, but the discovery is still significant.

Gene mutations DO occur over time in response to stressful or healthy environments
Long term traumas and persecution will alter the genetic makeup, but certainly not at the extreme level falsely reported for Scott Kelly. There have been several landmark genetic studies of Western Plains Natives, African Americans and survivors of the Nazi Holocaust in recent years, which clearly demonstrated that long term horrific environmental situations such as the near genocide of indigenous Americans, 250 years of slavery among African Americans or the centuries of mass murder of Jews affected current generations genetically. The most obvious effect is to reduce the ability of descendants to resist pathogens, inherited diseases such as diabetes and self-destructive behavior.
It has been long assumed that all social problems were caused by dysfunctional childhoods or toxic community environments. Thus, the approach to making the United States a healthier place to live during the mid-20th century was to pour vast quantities of federal funds into economic development programs. The best known of these programs were Tennessee Valley Authority, War on Poverty and Appalachian Regional Commission. All three programs resulted in dramatic changes in the physical appearance of communities, targeted by concentrated federal assistance.
Indeed . . . in 1930, a third of the people living in the Tennessee Valley of Tennessee had malaria. Bet you didn’t know that! Billions of federal funds offered free medical care for the malaria victims, drained swamps, constructed dams, killed mosquitoes, subsidized schools and created large industries, which raised the standard of living. Malaria is unheard of in that region now. As a result, eastern Tennessee is a hotbed of anti-federal government political attitudes. You go figure. LOL Meanwhile billions of dollars have been poured into Native American reservations for new schools and hospitals, plus such programs as free healthcare, free college education and even free food.
Yet . . . studies by the Centers for Disease Control in Atlanta have found astronomically high levels of inherited diseases and cancer among Native Americans, whose ancestors were subjected to relentless military persecution, being rounded up into reservations or being forced on the Trail of Tears. In all appearances, the descendants of these atrocities are light years better off than their ancestors, yet the genes they carry seem to be waging war on their host bodies. Diabetes, alcoholism, drug addiction and violence resulting from bipolar personalities are endemic on many Western reservations. In the three decades since casino revenue brought a flush of money to the North Carolina Cherokee Reservation, diabetes has exploded from occurring primarily among a minority of the elderly, who were obese, to a epidemic, which plagues 87% of the adults and an alarming, increasing percentage of teenagers.
The following article is written from the perspective of a descendant of Jewish Holocaust survivors, but also describes the parallel experiences of indigenous Americans. It is a thought-provoking essay. It does not propose any real solution to the problem of environmental genetic damage, but at lease it makes us aware of the true nature of this beast.
