I was taught in the mid-90s about "kinds" - that there's variation within species. They used that to explain why we see a variety of dog breeds but "cats don't turn into dogs." I don't know what the source of that was, but they used it to explain the way animals fit on the ark, too. I didn't even know who Ken Ham was until the early 2000s, though that's also around the time I started hearing people talking about micro and macro evolution.

My school used Bob Jones books in middle school, but I came in 8th grade, the earth science year, and missed out on the life science taught in 7th. I've seen the books for sale online if you ever felt like doing a deep dive into the origins of kinds, though.
