Choreographed Web-Building Routines Showcase Spiders' Architect Tendencies
(Inside Science) -- Like any good architect, an orb-weaving spider builds its residence in stages. Unlike human architects, however, they start without the final plan in mind. It's a strategy that always works for them, almost as if spiders are born knowing only the steps of a choreographed dance -- no pattern is revealed until it's finished. Scientists have observed the same structural progression in this construction process with many spider species, though elements such as silk thickness and location vary greatly.
