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

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?

It’s an instinctual behavioral, and we’re still studying how it works. We know that instinctual behavior is dependent on sensual stimuli (like it’s night time and the spider is on a branch) and different hormones.

What is interesting to me is that as humans we also have instinctual behavior dependent on our senses and hormones and I wonder how the differences in our modern way of life affect these behaviors.
