Why are scientists unable to see through darwinism? If you can manage to recover from fear at defying Big Science popery you can rapidly see the problem with a look at WHEE, starting above.
The ‘macro’ effect shows how evolution works in an example related we suspect to organismic evolution, thence the evolution of man.
Stop being snowjobbed by Big Science reps, and, quietly, alone, out of the ken of groups and group opinion, consider that the statistics of natural selection fails at step one (as Fred Hoyle patiently made clear) and therefore the whole Darwin paradigm is false, period.
From there, seeing random evolution failing, we can try to decipher an example of non-random evolution. We can see that it requires a ‘driver’ of evolution’, directionality, and this is visible in the example discussed: world history. It is helpful because the distracting crutch of ‘genetics’ is absent! Evolution is at a higher level than genetics!
