To put it in the most simple terms that even a biologist should be able to follow, if we are told that a football team has gained 1,500 yards on the ground while averaging three yards per rushing play, and we know that the maximum number of offensive plays per team per game is 84, then we know, beyond any shadow of a doubt, that the yards reported were not gained in a single 60-minute game. They could not have been. It is impossible.
The math is inexorable. The maximum number of yards that could have been gained on the ground in a single game, given a three yards-per-carry average, is 252. It does not matter if a desperate proponent of Neo-Schembechlerism proposes the idea that perhaps the team ran a hurry-up wishbone offense, or that the quarterback was a dual-threat as a runner, or that the team played in a league known for its terrible run defenses, or that one of the halfbacks is known to have one ripped off a 99-yard gain, or that NCAA teams have been known to play up to seven overtime periods, or that up to five different players touched the ball on the same play. The math is inexorable. The assertion that a football team which averages three yards per carry gained 1,500 yards on the ground in a single game is flat-out impossible. We can say with absolute certainty that it never happened without knowing any details whatsoever about the team or the game.
In like manner, the number of fixed mutations that are presently observed to distinguish two species, whether we contemplate modern Man and the Chimpanzee–Human last common ancestor (CHLCA) or the dog and one of the therapsids, are considerably – CONSIDERABLY – in excess of the maximum amount of time that could have passed since the speciation process is believed to have begun. There is only one defense against this straightforward mathematical observation, and that is the idea that enough parallel mutations happened very, very quickly to significantly reduce the average time per fixed mutation to permit it to happen in the intervening time period.
The problem here, of course, is that the numerical gap that needs to be filled is so large that if that were the case, then these mutations would be have to be happening so rapidly, and fixing in parallel so quickly, that we could observe evolution by natural selection happening in real time all the time.
But we don’t.
And, as predicted, the new advances in genetic science combined with new archeobiological discoveries are methodically reducing the already insufficient time in which evolution had to go from point A to point Z.
