Musings on Awareness 6 - Prof. G. Venkataraman


Awareness of Existence
God's greatest miracle is the human body. Although everything that exists is made up of atoms, a living being has the capacity for consciousness and self-awareness whereas inert matter does not. Scriptures say this capacity is characterised by a force, popularly termed as the “Life force”.
We all take our bodies for granted not realising what flexibility we have. Just watch a tennis match, ice skating or a ballet performance – amazing flexibility everywhere. Again, consider the human fingers. They can knit, paint, sculpt, perform surgery, and play all kinds of musical instruments, to name a few. The famous scientist Newton once exclaimed, “The thumb alone is enough to prove that God exists”.
We agree that the human body is packed with innumerable wonders; but in what way does that prove the omnipresence of God. This is where evolution comes in. The universe is a constantly evolving system and as far as we are concerned, there are three distinct stages of evolution that matter. We will concern ourselves with the third stage. About three billion years ago, life first appeared on Earth. Life slowly evolved from lower forms like plants and insects to more complex forms like fish, birds and animals. And, at the end, came man.
For every species of life form, there is a “gene”. At the molecular level, the gene holds all the information about the species and the particular individual in the series. For example, in the human being, the human genome not only holds all the characteristics that identify the being as human, but also the characteristics of the individual, such as the colour of the skin, eyes, facial features etc. This molecular arrangement can be disturbed by many factors, including radiation, and when that happens, we say the gene mutates. It could happen that the mutated gene could be the beginning of an entirely new species, evolution of species at a molecular level. Mutation is widely believed to be a random process. Charles Darwin said of evolution that “only the fittest of the newly emerging species survive, and evolution is thus a sequence of species that survive, coming one after the other”. This became better defined once the structure of the DNA was unravelled.
