I know Professor Dawkins is a scientist and therefore only examines evolution in the sense of what
has happened and can be measured or appraised using the many means and instruments that science provides, but it would be fascinating to hear if any scientists as gifted - or even nearly as gifted - as he has speculated about and tried to extrapolate the course that evolution might take in the coming thousands and millions of years.
It is generally accepted by scientists that life began on our planet over three billion years ago (unless, as some who tend towards the theory of panspermia believe, it originated elsewhere much earlier and was brought here in comets). Experts also believe that the Earth is likely to remain capable of supporting biological life for at least another billion years.
Evolution was very slow at first, but it brought great changes with it, completely transforming the atmosphere by pumping vast quantities of free oxygen into it and making it uninhabitable in all but a few protected pockets for the anaerobic life forms that had once dominated.
Their day passed, and the era of new forms of life dawned.
Is it conceivable that evolution will continue, perhaps accelerate or be artificially accelerated in the future? Look at the development that we have seen in electronics and quantum mechanics in the past 50 years and imagine what the development could be in the next 50, 500, 5,000 or 5 million?
It may be that just as the function of anaerobic life was to create the conditions for the life forms that succeeded it, our function may just be a transient one as well: to begin a process of development of non-biological life, that will eventually become self-sustaining and self-developing in ways that we could not even begin to understand.
Perhaps one day in the far future there will be sentient beings whose scientists research the faint traces of biological life that still exist and try, perhaps with little success, to enlighten those members of its civilisation who deny that they evolved from anything and insist that they were created as the are by a great universal spirit.
