Epigenetics?

[ElectricFetus]

This is not true. I created a scenario what would be blindly called random and natural selection but would be stem from cause and effect due to directed willpower or external inductions. This is where the brain overrides the predetermined 3-D DNA and alter the outcome due to want or necessity.

That has nothing to do with science of epigentics. What your stating is a philosophical question: does DNA determine fate, that a hard question to ask, because fate its self is questionable.

The Cambric explosion could be explained by epigenetic alternations on a smaller set of DNA.

How?

But that aside, you appear to more interested in the 3-D DNA. In the case of mind over matter to gain muscle, the genetic expression on the DNA has to increase for those genes that produce muscle and as well as amplified in all the support cells since the entire body has to grow in proportion. These are things the 99 pound self did not require. They both have the same base DNA, but the expression on the 3-D self is vastly different leading to more natural selection. Fossils cannot differentiate this very well.

What your describing is not a inheritable mechanism, just because we a genetically program with a degree of adaptability has nothing to do with epigenetics.

As an analogy, say you come home to the house and look around in the fridge and in the cupboards and you notice there is nothing good to eat. Another person who is good at cooking, uses the same set of, nothing to eat, and prepares an excellent meal. The ingredients or the genetic set did not change, only how they were prepped, spiced up and combined. It is this adaptability that allows life to quickly adapt and not have to remain linear until the next lottery.

Again has nothing to do with epigenetics.

epigenetics is the study of heritable changes in gene activity which are not caused by changes in the DNA sequence; it can also be used to describe the study of stable, long-term alterations in the transcriptional potential of a cell that are not necessarily heritable. Unlike simple genetics based on changes to the DNA sequence (the genotype), the changes in gene expression or cellular phenotype of epigenetics have other causes.

I was not focusing on one gene but on the spatial integration of many genes. If we start with a stem cell and induce it to become a novel variation somewhere between two normal cell types, we can create long-term alterations in the transcriptional potential of a cell that are not necessarily heritable. This is based on a cause and effect than may not occur normally. Why not alter stems cells in situ using internal potentials to get variations in body features that may not be inheritable, unless we recreate the same induced cause and effect.

I am less focused on post transcriptional modification of one gene, where the cell body improves the DNA output, in response to external potentials, creating new internal potentials leading to a new equilibrium.

If you took the DNA and randomly cut it in half would it combined with another random half allow a viable life form? Or does there need to be a certain level of coordination in the two halves to make sure we got all the parts? There needs to be cause and effect to choose wisely all the time with only minor gene errors and not 3-D errors.
