Evolution theory says that negative entropy in one subsystem causes negative entropy in another. That is absolutely contrary to the second law.
According to the theory a portion of a foundation species changes its DNA in response to external factors and becomes a new species. Medical science has shown unequivocally that adding or taking away a chromosome to/from a normal DNA sequence almost universally results in defects that are survival disadvantages.
That's something that stayed in my brain from an article about ten years ago. Current searches showed ranges from 98.8 to 99.07 %.
Except that organisms aren't part of a closed sub-system. There is a constant influx of energy from the sun.
Most evolution doesn't involve the addition or removal of a chromosome wholesale. It is the cumulative affect of much smaller genetic changes that result in speciation.
