How does each individual spider innately know what the architecture of their web should be without that knowledge being taught to them?

Question

Is that kind of information passed down genetically and if so, how does that work exactly? It seems easier to explain instinctive behaviors in other animals but weaving a perfectly geometric web seems so advanced it’s hard to fathom how that level of knowledge can simply be inherited genetically. Is there something science is missing?

I legit seen a spider in REALTIME Infront of my eyes swoop up an insect like some spiderman scene. What had happened was the higher up web had a “trap” or like a spot of web at the floor on the bottom. What was interesting was the spiders web wasn’t directly over the trap so the spider kind of reeled in the insect a small distance.
