Thoughts on Evolution
'A whale's flipper does not do the same job as a bat's wing,
Man creates. So how can we truly understand the mechanism of evolution? Why do we consider an experiment on the self-directed evolution of RNA enzymes as proof of natural selection, even though the conditions, including those for the selection process, have been designed by a scientist?
The theory of evolution is a unifying framework in biology. It has a complicated history, however, not because it is controversial among scientists, but because it provides a naturalistic explanation of why we are here, even who we are, humans, that is. The theory of evolution invokes an entirely natural rather than a supernatural mechanism - natural selection - to explain the origin of species.
Much is being written about chance and necessity, the pre-biotic origin of life, nature as a designer, or the value of biodiversity for the present and future survival of mankind, which is different from the survival of life as such. There is nothing in the theory of evolution that would indicate which combination of species is best suited for human survival. Since we do rather well today, the thinking is that preserving the status quo is indeed necessary and that species loss threatens the current ecological 'balance'. This thinking is understandable, since we can 'see' what we can loose, yet we are unable to see evolutionary innovation that may well create a new status quo equally suitable to human existence.
Evolution is not about ...
Evolution works because ...
And keep in mind ...
