Neoteny: First of the Noteworthy Words

This is the first of a new category (or Label) for me called Noteworthy Words. It may or may not last very long, though it's seldom been said I was short of words!!! I used to think that I knew what neoteny referred to from when I took an entomology course in the college where I worked many years ago (how often does the word come up in my life?), but I was mistaken slightly about the meaning. It seems that it does not refer to the Newness (or babyish appearance) of young animals, but is instead a word used to refer to the survival of some aspects or appearances of the young in a mature animal. The word's still interesting and still comes up damn seldom, but it sticks in my craw that I DID NOT (as I egotistically presumed) know what it meant! Shitfire! (Not to put too fine a point on it!)

p.s. There are also evidently some specialized kinds of neoteny (medical, psychological) that I ignored because I don't want my brain to explode, thank you very much!
