Are Genes Our Destiny? Scientists Discover 'Hidden' Code in DNA Evolves More Rapidly Than Genetic

Once again, the more we learn, the more we learn we don't know. Someone's genetics can be exactly the same as another persons, but the difference is in the genes that are activated in one and silenced in the other.

So changes in "gene expression" can occur very rapidly, not based on the genes themselves, but based on the activation or silencing of the same genetic code through a very few generations of the species.

It makes sense because we develop areas of our body that we use, and become undeveloped in areas we don't use. So the next generation may experience activation in the genes we used based on rapid epigenetic changes.


"Our study shows that it's not all in the genes," said Joseph Ecker, a professor in Salk's Plant Molecular and Cellular Biology Laboratory, who led the research team. "We found that these plants have an epigenetic code that's more flexible and influential than we imagined. There is clearly a component of heritability that we don't fully understand. It's possible that we humans have a similarly active epigenetic mechanism that controls our biological characteristics and gets passed down to our children. "



With the advent of techniques for rapidly mapping the DNA of organisms, scientists have found that the genes stored in the four-letter DNA code don't always determine how an organism develops and responds to its environment.



In fact, many of the major discoveries that led to these conclusions were based upon studies in plants. There are traits such as flower shape and fruit pigmentation in some plants that are under the control of this epigenetic code. Such traits, which defy the predictions of classical Mendelian genetics, are also found in mammals. In some strains of mice, for instance, a tendency for obesity can pass from generation to generation, but no difference between the genetic code of fat mice and thin mice explains this weight difference.




Ecker said the results of the study provide some of the first evidence that the epigenetic code can be rewritten quickly and to dramatic effect. "This means that genes are not destiny," he said. "If we are anything like these plants, our epigenome may also undergo relatively rapid spontaneous change that could have a powerful influence on our biological traits."

This article makes me wonder about the "shift" or whatever is maybe going to happen. One of the theories was a human evolution wasn't it?

It explains why we can share 96% of our DNA with a chimpanze, but be so dramatically different.

or techno-logically matrixes for time-loops
we are in a time loop, right?

A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation.

Programmed Evolution I guess ???

So basically, determinism can't be supported as genetic determinism, and some kind of catalyst could, very rapidly, change the biology of a human or other organism. So evolution is easy?

It appears to be that way. Rapid evolution based on the epigentic coding...

How are we so different from chimps exactly?

Chimps don't destroy their own environment.

Different breeds of dogs show vastly different behavior too..
