Chicago (White, middle/working class) suburb, born in 1974, graduated high school in 1992, attended public school the whole way.
I don’t recall anything coming up in elementary school. I don’t think it entered our minds at all. We were fascinated with dinosaurs, as all kids are, and visited the Field Museum of Natural History and the Museum of Science and Industry once a year on field trips, but I don’t recall anything about evolution.
Jr. High Biology was when I first saw a Punnet Square and learned about fruit flies and peas, and the Survival of the Fittest theory. Darwin and the finches and all that.
I can’t recall if it was in Jr. High or High School that Punctuated Equilibrium and Lamarckian Evolution were brought up. Both were only brought up to be immediately shut down as things that people used to think, but we now know aren’t so. Now we know (we were taught) that evolution is a very slow process due to random mutations being slightly advantageous that gradually create different species - except when it isn’t, like those soot colored moths. I know know that Punctuated Equilibrium is both newer and not so thoroughly debunked as we were taught, and that it’s a form of gradualism, not its opposite. So, they kinda got that wrong (or I learned it wrong.)
The paragraph on Lamarck contained an illustration of a rat and a rat with a cut off tail, woodcut style. Funny how I can still see that in my mind’s eye.
I did believe in a God at that point, but never questioned evolution. I believed in God the Watchmaker, who stirred the primordial soup and gave it the spark of life and then sat back to see what happened. Nothing I was taught invalidated that, but neither did it encourage it.
Creationism? Never mentioned. Like others, I was shocked sometime in college to discover that there were real Creationists. Then I thought they must be a sliver of a fraction of a minority. I’m still shocked every time I read something like 42% of Americans are Creationists. I mean…really?! Yes, exactly like finding out that people still believe the world is flat.
I don’t recall if it was something I was told, or something that I figured out on my own, but I assumed growing up that the “days” in Genesis were very long days. Or rather, that God was beyond the human concept of time, so He could make a Day as long as he needed. (Similarly, I believed that the centuries that some of the really old dudes lived in the Old Testament were similarly fuzzy measurements of time, because God doesn’t use our calendar.) I was not raised religious, but was very interested in The Bible, so read it on my own.
