Notion of random evolution. (E O M - 9)

Myth Conception 4: 

(Ref. Book – Excerpts from Spontaneous Evolution, Authors: Bruce H. Lipton and Steve Bhaerman)

As repeatedly propagated by Swami Vijnananand, we have been mentioning in these blogs the role of mind and the importance and inevitability of mind's role for inclusion in the scope of science. Such opinions are echoed by a few scientists and thinkers in the 21st century. This blog also covers this topic.

Jean-Baptiste de Lamarck born in 1744, for the first time published the theory of evolution in three volumes based on his ten years research. Lamarck’s idea about evolution and nature’s impulse toward perfection gained prominence in France. Lamarck suggested that evolution was the result of organisms acquiring and passing on environment-induced adaptations needed to sustain their survival in ever-changing world.

Unfortunately for Lamarck, his ideas about evolutionary progress being part of the course of nature had social implications. If nature could progress, then it was natural for lower classes of humanity to progress as well. So when the French revolution failed and King Louis XVIII restored the monarchy, Lamarck found himself out of favor with the church and ruling class. For some reasons his academic rival Baron Cuvier purposefully distorted and misquoted Lamarck’s work on evolution. Cuvier’s assessment of Lamarck and his ideas has ever since been (1832) cited as the document that justifies portraying Lamarck as buffoon (joker/ fool).

Ironically more than 175 years after Lamarck’s death (in 1829) science is finding that evolutionary intention may be a lot closer to the truth than Lamarck ever imagined. But between then and now other scientists also managed to push Lamarck and his ideas further into background. The Darwin evolution theory (survival of the fittest) was considered appropriate and acceptable.

The experimental science of genetics was officially launched in 1910. Later Thomas Hunt Morgan and in 1943 researchers Salvador Luria and Max Delbruck appeared to prove once for all that mutation was purely random event. Later up to 1988 many experiments confirming these findings led science to adapt the assumption that all mutations were random events.

Based upon these observations science adapted the seemingly iron-clad tenet: when mutation occur they are purely random and unpredictable events and have nothing to do with any need the organism might have at present or in the future.

Because evolution appeared to be driven solely by mutations, science concluded that randomly drawn evolution has no purpose. The idea fit wel with the scientific materialism’s belief in purely materialistic Universe and helped shift the focus from intentional creation to merely “throw of genetic dice.” A human being is just another among the “accidental tourist” who materialized in the biosphere through random act of heredity.

However in 1988, promonant geneticist John Cairns challanged sciences's established belief in random evolution.Cairns novel research on " The Origin of Mutants" was published in the presigious British journal Nature.

Cairns referred to this newly discovered mechanism as directed mutation. But the concept of environmental stimuli feeding back into an organism and direct a rewritting of genetic information was strongy disliked by the dogma of the conventional science.

Both Nature and the Amrican journal Science publised editorials raging against Cairn's findings. This was a clear indication that the white-coated prists of scientific materialism were ready to burn Cairns at the stake.

Over the next decade other researchers replicated Cairn's results. As a result, leading genetic researchers softened directed mutation to adaptive mutation and the relegated to beneficial mutation.

Cairn's work and subsequent studies introduced the realities that organism not only adapts to an environment but that they intentionally change their genetics to enhance the adaptation of future generation. In other words, science is coming to realize that evolution is not simply an accident as per Darwinian theory but a coordinated Lamarckian dance between an organism and its environment, a dynamic process in which organisms can continueously adapt to stressful circmstances.

In a way, evolution is a random process but the randomness seems to have a purposeful destnation.

We shall later see the views expressed by Swami Vijnananand when he guided to the young seekers of Manashakti Ashram in 1990 on the direction of the research needed to find the truth behind the process of evolution. But here one may take a note that Mind's role in evolution has to be considered as "pure materialistic attitude" is not acceptable to the conventional scientists too!
