Societies would _not_ be better off if everyone were like Mr Spock, all rationality and no emotion. Instead, a balance – a teaming up of the internal rivals – is optimal for brains. … Some balance of the emotional and rational systems is needed, and that balance may already be optimized by natural selection in human brains.
In short, evolution is as close to being a scientific fact as is possible for any theory, given that science is open – ended and no one can predict with certainty what may change in the future. The prospect that evolution by natural selection, at least as a broad mechanism, will be overthrown in the future is about as likely as the prospect of finding out some day that the Earth is really flat. Unfortunately, those who regard these scientific facts as a threat to faith have chosen to distort and misrepresent them to the public.
Truly, this earth is a trophy cup for the industrious man. And this rightly so, in the service of natural selection. He who does not possess the force to secure his Lebensraum in this world, and, if necessary, to enlarge it, does not deserve to possess the necessities of life. He must step aside and allow stronger peoples to pass him by.
There is economics in biology, nothing is free, everything has to be paid for, there are costs as well as benefits to everything in life, for example, there was never sufficient natural selection pressure to develop better eyes, individuals could earn other things like smiley smiles rather than waste energy & time on better eyes.
Professor Eddington has recently remarked that ‘The law that entropy always increases – the second law of thermodynamics – holds, I think, the supreme position among the laws of nature’. It is not a little instructive that so similar a law [the fundamental theorem of natural selection] should hold the supreme position among the biological sciences.
Natural Selection is not Evolution. Yet, ever since the two words have been in common use, the theory of Natural Selection has been employed as a convenient abbreviation for the theory of Evolution by means of Natural Selection, put forward by Darwin and Wallace. This has had the unfortunate consequence that the theory of Natural Selection itself has scarcely ever, if ever, received separate consideration.
An argument often given for why Earth couldn’t host another form of life is that once the life we know became established, it would have eliminated any competition through natural selection. But if another form of life were confined to its own niche, there would be little direct competition with regular life.
If it takes several billion years to develop the building blocks which you need, like RNA and DNA, and then those can build multicellular life and then multicellular life can be honed with natural selection to a point where it becomes sentient like us, then at some point that sentient being can begin to manipulate the matter around it to build better sentient life.
