In biology class, biology wasn’t presented as a quest for the secrets of life. The textbooks wrung out the questing. We were nowhere acquainted with real biologists, the real questions they had, the real experiments they did to answer them. We were just given their conclusions.
So is every subject textbook? It's so prevalent I don't even think it's a problem with textbooks, as I also don't think most people would care regardless of how much amazement you'll pump into your materials, but rather how they scarcely offer any "further reading" recommendations for those who'd care. My biology textbook didn't, same with geography. Chemistry, lit, and history did at times. Physics did, but we used Halliday-Resnick-Walker. Maths and CS were based on the teacher's handouts, so it fluctuated. Can't recall the rest. In any case, the remedy for curiosity, in both meanings of the phrase, is to ask the teacher. Hell, better ask (and teach kids to ask) the librarian; it's literally what they're there for and will be ten times more eager to assist.
More to the meat of the article, IMO biology suffers from being taught in parallel with other science subjects without much connection, yet requiring so much from other disciplines there's probably no other way to do it at all. For the mechanism of how the gene expressions/proteins happen, you need biochemistry, which itself requires a pretty in-depth understanding of electrostatics, Van der Waals potential/forces (it's just a negative gradient, bro), diffusion, and valence electron shells/reading electron diagrams. And, you know, some organic chem wouldn't go amiss either. It comes with a heap of prerequisites if you want to be at all thorough and base your course on deep mechanical understanding, many of which are honestly unreasonable to assume even in most AP folks.
Dunno, maybe I'm just meandering around the problem or didn't understand the article's point, but in this day and age, there aren't many non-material excuses to not finding curiosity-spiking amazement-inducing presentations. Sieving out bullshit, however, is a different thing.
