I have a simple way of demonstrating the fallacy of macro-evolution. In order for macro evolution to be true (appearance of a new species) there has to be born at approximately the same time both a male an female of this new species, with the exact same mutations, in the same location, both survive to maturity, find each other, reproduce successfully, and raise enough of their young to survive amongst what would likely be numerous predators.
One need not delve into the mathematical improbabilities/impossibilities to recognize that macro-evolution is simply an untenable position.
LOL - definitely quicker and easier.
Your method is reasonable, logical and acceptable to most. However, the proof still lies with mathematical improbabilities/impossibilities. This is what is inferred by your example, but to be proof, the math has to done.
