Evolution


Evolution is the change in inherited characteristics of biological populations over successive generations. Evolutionary process gives rise to diversity at every level of biological organization, including species, individual organisms, molecules such as DNA and proteins. Charles Darwin and Alfred Wallace were the first to formulate a scientific argument for the theory of evolution by means of natural selection. In 20th century, genetics was integrated with Darwin’s theory of evolution by natural through the discipline of population genetics. Evolution by natural selection is a process that is inferred from 3facts about populations –more off springs are produced than can possibly survive, traits vary among individuals leading to different rates of survival and reproduction, trait differences are heritable. Natural selection is the only known cause of adaptation, but not the only cause of evolution. Other non adaptative causes of evolution include mutation and genetic drift.

According to Hindu creationism all species on earth including humans have devolved or come down from a high state of pure consciousness. Hindu creationists claim that species of plants and animals are material forms adopted by pure consciousness which live an endless cycle of births and rebirths. According to Hindu creationists the universe may even be older than billions of years. These views are based on Vedas which depict an extreme antiquity of the universe and history of the earth.

The overall probability of forming one protein molecule by random chance process is 9.31x10^(-152). It has been recently determined that a minimal functioning cell has no fewer than 256protein coding genes. Considering proteins only, probability of complete living cell coming into being through random, chance process would be 10^(-40023). The whole universe consists of only 10^82 atoms and the universe is less than 10^18seconds (if universe is taken to be 13.77billion years then 4.34x10^17seconds). So we give much credit to chance, luck plays a big role in the evolution process. The first life form existed 3.6billion years ago which is 3.2x10^17seconds after big bang and the earth formed after 2.89x10^17seconds after big bang. The overall density of our known universe is only 10^-31gm/cc.






















The size of the universe when the life formed or during the initial primordial soup changes over a factor of 1000at the max. The number of reactions required to get the probability of forming the protein chains to form the simplest living entity is according to the modern scientists is near zero, but not zero. Then for the theory of natural selection to take place, the probability of the subsequent events will go closer to zero probability but never reach there. The important fact among the scientific community is that they never contradict one another. Every branch works independently to bring out new theories to support their fellows so that the booming industry can survive without ever reaching the truth.

The scientists will always try to reach the truth, but never get the truth. The truth apart, the Grass is supposed to have retained its position through the evolutionary cycle and is the most widespread form of plant life. Grass is food many of the herbivorous animals and is a medicine. Medicinal value is better down from the animals as observed by the sages. When there are stomach problems for cats and dogs, they eat grass and vomit what they have eaten. Cats and dogs apart, the grass has been undergoing severe pains during the times it eaten by the animals, insects, worms, etc.

The grass we see on our laws is the same great-great-grand father to the sugarcane and also for the bamboos too. But the lawn grass continues to exist to us to jump on it. The laws of natural selection have been cruel to the grass and plants in general.  May be in the future, the grass will develop mobility, wings and they may fly, move away when we want to sit on them. In the worst case, the blades of grass may attack when humans or animals tend to go near them. The evolutionary process has never stopped and will never stop. It is only a matter of chance; one day grass is put in the docks and accused of murder. The scientists then say it’s part of evolution and the DNA is modified by some virus and come with new formulas to prove their point, saying that when the temperatures reach near certain value, the virus is at certain areas on the grass, the DNA is attacked at a particular point, blah, blah,… the grass will awaken and become a killer.

The scientists will be awarded Nobel Prize for coming with another beautiful theory. Many scientists are busy developing complex systems to simplify our lives but only in the end to make it more complex while few scientists are working to create simpler systems. The tendency of discarding simpler systems is called modernization, progress which involves creating new and more complex problems to solve the existing problems. The people are made believe the solution is near, but never achieved. We are waiting for to miracles to happen when the Grass will also contest elections.
