El Mito del ADN Basura

Aun hay evolucionistas hablando de esa basura



Un libro que promete ser controversial como lo fueron, Darwin's Black Box de Michael Behe y Signature in the Cell de Stephen Meyer, es el "The myth of junk DNA" o "El Mito del ADN Basura" escrito por uno de los mas importantes proponentes del diseño inteligente Dr. Jonathan Wells.

En este libro se argumenta como los descubrimientos científicos han acabado con el mito de que existe ADN basura, que no tiene alguna función, cosa que era una predicción que se basaba en la teoria de la evolucion.

El Dr. Wells tiene dos doctorados, uno en Biología Molecular y celular de la Universidad de Berkeley en California, y otro en estudios religiosos de la Universidad de Yale. A trabajado como investigador postdoctoral en la Universidad de Berkeley y como supervisor del laboratorio medico en Fairfield, California, además de que ha enseñado biología en la Universidad del Estado de California en Hayward.



Esta es una interesante descripción del libro:

"Un alto numero de importantes proponentes del Darvinismo afirman que "el ADN basura", la sección que no codifica la proteína en el ADN compone mas del 95% de nuestro genoma- provee evidencia decisiva para la teoría de Darwin contra el diseño inteligente, ya que un diseñador inteligente no podría haber llenado nuestro genoma con tanta basura. En el "Mito del ADN Basura", el biólogo Jonathan Wells exponen esas afirmaciones como un mito anti-científico que ignora la evidencia, que se basa en ilegitimas especulaciones teologicas e impide el avance de la investigacion biomedica. Muy lejos de consistir de basura, el genoma se ha relevado incrementalmente a si mismo como un sistema integrado, multidimensional en el cual las secciones no codificantes de proteína desempeñan una amplia variedad de funciones biológicas esenciales. Si algo prueba el genoma actualmente es evidencia de diseño inteligente, no evidencia contra el. Después de leer este libro, su opinión respecto al genoma, y de las personas que se proclaman como representantes de la ciencia mientras ellos la mal interpretan, nunca sera la misma"


Algunos comentarios positivos respecto al libro de otros científicos (En Ingles):


In The Myth of Junk DNA, Jonathan Wells draws together published evidence over the past decade which clearly pulls the rug from under the concept that the majority of the human genome is ‘junk DNA’ (functionless DNA). Breathtaking discoveries since the publication of the Human Genome Project in 2001 have demonstrated that most, if not all nuclear DNA is transcribed.

The proponents of Darwin’s theory claim that junk DNA provides evidence for Darwinian evolution as it represents molecular accidents which are the indelible signatures of evolutionary histories. This argument now has been turned on its head.

I strongly recommend The Myth of Junk DNA, a lucid account of the evidence that junk DNA has many diverse biological functions. It is an important reference source with an excellent bibliography and notes. The Myth of Junk DNA clearly demonstrates that the concept of junk DNA is now dead.

“Jonathan Wells has clearly done his homework. In The Myth of Junk DNA, he cites hundreds of research articles as he describes the expanding story of non-coding DNA—the supposed ‘junk DNA.’ It is quite possibly the most thorough review of the subject available. Dr. Wells makes it clear that our early understanding of DNA was incomplete, and genomics research is now revealing levels of control and complexity inside our cells that were undreamed of in the 1980s. Far from providing evidence for Darwinism, the story of non-coding DNA rather serves to increase our appreciation for the design of life.”

“Citing hundreds of peer-reviewed articles which show that more and more of the genome is functional, Jonathan Wells delivers a powerful and carefully researched broadside against the ‘junk DNAhypothesis.’ Even biologists who firmly reject the notion of intelligent design must surely acknowledge on the evidence presented in this timely book that appealing to ‘junk DNA’ to defend the Darwinian framework no longer makes any sense.”


Michael Denton, Ph.D.
Medical Geneticist and Author of Nature’s Destiny
“This is an excellent and in-depth discussion of several key points of the subject of ‘junk-DNA.’ The author shows for many prime examples still advanced by leading neo-Darwinians that the ‘Darwin-of-the-gaps’ approach doesn’t function or is at least doubtful.”

“There is a box in the biological sciences into which all evidence must be placed. That box is called Darwinian evolution. In The Myth of Junk DNA Jonathan Wells tells the intriguing story of ‘junk’ DNA—the idea that non-protein coding DNA, which accounts for the majority of the DNA in the genome, is non-functional and without purpose; the result of the unguided purposeless process of random mutation and natural selection that produced it. In recent years, however, numerous researchers—not necessarily opponents of Darwinian evolution or advocates of intelligent design—have discovered many functions for non-protein coding DNA, which are thoroughly reviewed by Wells in this book. Unfortunately, in their effort to keep the ‘junk’ label attached to non-protein coding DNA so that it remains in the box of Darwinian evolution, a number of prominent Darwinists continue to insist, in spite of the recent results to the contrary, that it is largely left-over waste from the evolutionary process. As Wells clearly demonstrates in his book, this dogmatic commitment inhibits the scientific process. Science needs to be guided by objective evaluation of the evidence, and scientists should not allow their thinking to be arbitrarily restricted by dogmatic ideas. We need scientists who think outside the Darwinian box. Wells’s book not only informs its readers of very recent research results, but also encourages them to think objectively and clearly about a key discovery in biology and to approach biological research with more creativity. It is a great read.”


Russell W. Carlson, Ph.D.

“For years, Darwinists have claimed that most DNA is left-over detritus from failed evolutionary experiments. This ‘junk DNA’ has been offered as evidence for Darwinism and evidence against intelligent design. The only problem with the claim, as Jonathan Wells shows in this fascinating book, is that it’s not true. Careful scientists have known for some time that the non-coding regions of DNA have all manner of function, so it is surprising to see prominent Darwinian scientists and their spokesmen continue to push the party line. Now that the evidence against the junk DNA story is indisputable, its defenders will want to beat a hasty retreat. The Myth of Junk DNA will make it hard for them to cover their tracks.”

  1. En este libro se argumenta como los descubrimientos científicos han acabado con el mito de que existe ADN basura, que no tiene alguna función...

    No es un mito. La existencia de DNA basura es universalmente aceptada. El debate es sobre qué porcentaje del genoma este realmente ocupa.

    Por otra parte, la existencia de DNA basura no tiene absolutamente ninguna relevancia sobre la posiblidad de que los seres vivos hayan sido "inteligentemente diseñados". No hay ninguna razón para suponer que el/la/los/las diseñador/a/es/as haría(n) organismos perfectamente eficientes y libres de elementos superfluos como el DNA basura. Además, como no se conocen los propósitos de tal entidad o entidades, es absolutamente imposible determinar si un elemento está "bien diseñado" o no.
