Take a penny, double it each day for a month... see what you end up with.. Factor in twins and triplets and reassess.. You must have neglected your cyphers when young, Jethro....
There’s a BIG difference between multiplying pennies (essentially functionally and physically identical, each unit-wise) vs. biological multiplication via sexual reproduction. If the same genetic stock is multiplied over and over again, it results in increasing incidents of genetic defects. Look at the Pakistani kissing-cousin communities in Britain, to witness how bad it can get with just a few generations.
You must have flunked biology, Samson.
