How did spiders learn to manufacture advanced microelectronics? Victor Ortega-Jimenez told UC Berkeley, “Electrostatic charges are everywhere, and we propose that this may have driven the evolution of specialized webs.”1 But has anyone ever observed electrostatic charges being the catalyst for the invention of new technology?
