The Process of Evolution – Too Good to be True?
If the process of evolution sounds too good to be true to you, consider the following:
1) Even when millions of species exist in the world today, 99.9% of all species that has ever lived have gone extinct, with each of them typically taking 10 million years to become extinct, in a period spanning 600 million years, and
2) The unbroken chain of survival from first cellular organisms to the current highly evolved organisms for a period of 600 million years has become possible by the fact that survival instinct, being one of the features of evolution, has been dynamically working in all organisms, offering each of them survival on a moment-by-moment basis by interacting with the external world, interacting internally, changing location, etc., while reproducing themselves, reproduction being another feature of evolution.
Level of Design: One of the best proofs of theory of evolution is that it "designs"organisms only up to the level where they can survive and reproduce effectively in their environment, nothing more and nothing less.
In detail: As the theory of evolution predicts, the evolutionary process only designs organisms with characteristics that are sufficient enough for them to survive and reproduce based on their own changing conditions and environments, and not all the characteristics necessary for survival and reproduction. In other words, such designing processes are to the effect where they neither strive for excellence nor are weak enough to not to work for the purpose of survival and reproduction.
What makes the proof robust is that a large number of organisms are not straightforward and simple, but are most intricate mechanisms in the known universe, and demonstrate the above effect in whatever complex operations they perform, which also change dynamically based on their changing survival and reproduction requirements.
Intelligent Designer: Not considering the theory of evolution results into the belief that organisms are a product of an intelligent designer.
The reason? Excluding living organisms, any intricate and sophisticated mechanisms encountered by us where multiple entities work together to reach common goals are in man made machines, which need an intelligent designer. E.g., all parts of a car engine are designed to work together to reach the common goal of propelling the car. This results in the intuitive belief that wherever there is intricate and sophisticated mechanism, there has to be an intelligent designer. Additionally, based on the "common sense" that intelligence of the one who creates has to be more than the created product, it seems that to design an intelligent product like a human being, you need a super intelligent designer.
If there were a super intelligent designer, based on the notion that we are the "most evolved" species, at least us humans would have been made of the best possible non-destructive material, would have 360 degree wraparound eyes and the phenomenon of pain would be replaced by a data constrained mechanism, amongst hundreds of other things.
With gazillions of organisms demonstrating the effect of natural selection through the common cause of survival and reproduction instincts on an ongoing basis since the history of evolution spanning hundreds of millions of years, it is only common sense that suggests that such a pervasive effect is not possible in any other way.
