This will be as brief and as simplistic as possible for obvious reasons.
Humans share approximately 98.5% of their DNA with chimpanzees. So, for this example we will need to temporarily accept the premise that DNA can be mutated (changed) by at least 1.5%. The problem is that mutations are entirely random meaning that a mechanism potentially capable of mutating ~1.5% of a chimpanzee’s DNA to exactly match human DNA could also mutate it 1.1% or 0.45% or 0.37940%, or 1.20238943029423%, or 1.49% or 1.499% or 1.4999% or 1.49999%, or 1.499999%, or 1.4999999%, or 1.49999999%, or 1.49999999999999999999999999999999999999999999999999999999999999999999…%, etc., ad infinitum, and in a virtually infinite number of “directions.” (This is known as an infinite series in calculus.) And, since there are only a finite number of specific genetic codes which could produce a human, to quote Douglas Adams, “any finite number divided by infinity is as close to nothing as makes no odds…” (And, that’s without mentioning that 98.5% is an average, meaning that slightly more or less DNA can be shared between certain individuals of both species.)
