Spider webs break, repair don't replace

From Nature(full article here)

A web's strands of silk adapt to the amount of stress they experience, and how that stress is loaded onto them. Under a light stress, a gentle highland breeze perhaps, the silk softens and extends, so allowing the web to retain its structure. But when a larger and more disruptive force strikes — such as a hand groping for a light switch in a dark attic — the silk strands first extend, then the most stretched of those strands become suddenly rigid and so break. This sacrifice of a strand or two localizes the damage, and keeps the rest of the web intact. Once the disturbance has passed, the spider can scurry out to repair the web, rather than being forced to rebuild.

How to make the analogy to an adoptive network?
