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?

Answer 1

I wouldnt be surprised if it had to do with geometry itself. Ive seen many strange webs. They are not always perfect. As long as they work. The webb we deem perfect is most durable and it covers the largest surface, also it probably has most “alert lines” and it easiest for a spider to move across it and to make.
