Genes, Epigenetics and Biodoomsday By Brian Simpson
It was once thought that the only genetic changes possible were those carried by genes, which were separate from the environment, except when random genetic mutations occurred, which then changed the genes, allowing evolution by natural selection to occur. Then came epigenetics:
“that genetic changes caused by environmental factors may be passed down from one generation to another. According to a team of researchers at the European Molecular Biology Organisation (EMBO) in Spain, the genetic changes may even be inherited by up to 14 generations thereafter. The experts have examined the genetically engineered nematode roundworms called C. elegans in order to carry out the study. The roundworms are known to carry a specific gene that makes them glow bright under ultraviolet light once it is activated.
The research team initially changed the temperature of the animals’ containers to 68 degrees Fahrenheit. The experts have observed that the gene reduced activity, and that the nematodes hardly glowed at all. The scientists have then transferred the worms to a warmer temperature of 77 degrees Fahrenheit. This resulted in the activation of the fluorescence gene that made the worms glow like Christmas lights. The experts have also observed that the worms continued to glow when they were moved back to a colder temperature.
The scientists also examined the worms’ offspring for up to seven generations and found that the baby worms appeared to have inherited the epigenetic genes for a warmer climate despite not being exposed to such temperature changes. The research team has assessed the animals further by exposing five generations of nematodes at 77 degrees Fahrenheit and then exposing the other half of their offspring to colder temperatures. The results have shown that both groups exhibited high fluorescence gene activity. The mechanism behind the worms’ response remains unclear, but it appears that the effects might be a type of biological forward-planning, researcher Adam Klosin has reported.”:
Environmental activities can alter inheritance, such as in the case of “metabolic programming,” where an obese pregnant female may transfer via tsRNA (toxic small RNA) the propensity for obesity to the embryo:
There are numerous other cases of epigenetic effects:
The big issue here is given the highly toxic world which has been created, is there a genetic time bomb being set up, putting a shelf life on the human species itself? Is there some sort of toxic genetic build-up that would reduce the viability of the human genome? Is the decline in sperm quality and quantity, part of this?
