Life results from the non-random survival of randomly varying replicators. The watchmaker is blind
The river of my title is a river of DNA, a river of information, not a river of bones and tissues
If you want to do evil, science provides the most powerful weapons to do evil; but equally, if you want to do good, science puts into your hands the most powerful tools to do so
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.
What really happens is that the gene pool becomes filled with genes that influence bodies in such a way that they behave 'as if' they made complex, if unconscious, cost/benefit calculations
It is almost as if the human brain were specifically designed to misunderstand Darwinism, and to find it hard to believe
The replicators that exist tend to be the ones that are good at manipulating the world to their own advantage. But other replicators are also successful otherwise they would not be common. The world therefore tends to become populated by mutually compatible sets of successful replicators, replicators that get on well together
The trouble with conspiracies, even those that are to everybody's advantage in the long run, is that they are open to abuse. If manipulators really had the powers claimed, they could win the lottery every week. I prefer to point out that they could also win a Nobel Prize for discovering fundamental physical forces hitherto unknown to science.
