Currently, and the number grows daily, over 100 million trillion (100,000,000,000,000,000,000) genetic transmutations were required for the last prehuman to evolve into the first human being. So far, we have found 173, which, incidentally, means the prehuman could have also evolved into a horse or snake or whale or barnyard pig.

This is so hysterically funny and massively poignant, that nothing more needs to be said on the subject of genetic transmutations.
