Elsie: " Then; logically, there MUST be innumerable little doodads and hickeys attached to creatures today that will NOT make it to the next generation.
Where are they?? "

Surely you already know, those "doodads" are found in every generation's DNA, right?
They're called mutations and every generation inherits both the accumulated stock from the past and a small number of new ones.
The vast majority of mutations to non-coding DNA are harmless, nearly all to coding DNA harmful in natural selection, but a small number helpful.
Those are the beginnings of adaption & evolution.

All of which I'd guess you already know, but chose to mock it, for what reason?

Easy answer: To SHOW that mere 'dna' differences are NOT producing any VISIBLE changes to creatures.
