Orb weaver spider glue properties evolve faster than their glue genes, scientists find

Spiders that don't weave good silk don't get to eat. The silk spiders produce to create their webs is key to their survival—but spiders live in many different places that require webs fine-tuned for local success. Scientists have now studied the glue that makes orb weaver spiders' webs sticky to understand how its material properties vary in different conditions.
