As for your “profits first conseuquences later” idea. And those traits can be passed on to our progeny. The epigenetic Epigenetics is not a source of variance, it is part of the mechanism whereby certain environmental factors or experiences have their effects. The environment can affect genes through the process of epigenetics, where genetic expression (phenotype) is changed without changes to the underlying genetic structure. A lot of these changes are epigenetic (The methylation or demethylation of DNA)- meaning that the environment changes our genes and then we pass those changes on. In short, most chronic health problems are not rooted in the inherent makeup of our genes, but in how our environments shape and drive and alter gene function and expression. Researchers in the field of epigenetics, a new(er)form of science, are finding that our genes are shaped, at least partly, by how our ancestors lived. This is the most common cause of Turner's Syndrome, which I discuss in chapter 8 (X-Women) of Epigenetics: How Environment Shapes Our Genes. The World Around You Shapes Your Genetic Expression The other import point that was not discussed in the paper is the role of the environment in phenotypic disease influences—our diet, our level of stress, our exposure to toxins, our level of physical activity—the list goes on and on. New research suggests that epigenetic factors -- chemical "switches" attached to genes that turn them on or off -- are a more plausible heritable mechanism behind homosexuality than DNA itself. The epigenome is affected by everything from diet to environment to lifestyle choices. Well I'm not qualified to talk about business in any way shape or form, I'm a science guy through and through. Whether or not homosexuality is determined by epigenetic changes remains to be seen. You can see where from an American perspective those of us who know these things are scared . Our genes are not our fate, because epigenetics! I certainly don't know that, but what I do know is that somewhere in the line of our families, a gene was mutated by it's environment, diet and/or thoughts.epigenetics. But we did not know that we are genetically who we are because of environments that our ancestors lived in. For the first time since DNA was discovered, epigenetics has encouraged scientists to move from genetic determinism to studying how the environment can shape our lives. Such-and-such Waddington's new term incorporated the idea of a genetic profile, which shapes the metaphorical landscape over which each individual developing organism travels, channeling them with greater or lesser probability toward certain outcomes. If we can change them in the first place, The new science, however, reveals that your perceptions control your biology, and this places you in the driver's seat, because if you can change your perceptions, you can shape and direct your own genetic readout.
