[Well, spontaneous mutation and natural selection within species is fact. However, the notion that primitive species evolve into more sophisticated species is not fact. In fact, it appears to violate the second law of thermodynamics.]
As a mechanical engineer with a solid background in thermodynmics, that is absolutely false. The second law allows local increases in order at the expense of global disorder. This is why you can evolve from an embryo to an adult, else by your analysis only stasis would be possible.
Of course it’s a stupid argument, but you’ll see it here a million more times by those who want their conclusion, and are willing to make up any crap they think supports it.
Granted. In the case of the embryo, DNA provides the script. A magnificently sophisticated organism reproduces. How is this analogous to an slime mold evolving into a human? It is counter intuitive and anti-intellectual to simply accept that. I grant you that it is "possible."
