Nature-Inspired Science: Innovations Borrowed from Biology

Nature, honed by billions of years of evolution, offers a treasure trove of ingenious solutions to complex problems. Biomimicry—the practice of emulating biological designs and processes—has sparked groundbreaking innovations across diverse fields. From spider silk-inspired materials to drone designs modeled after birds, these technologies reflect humanity's ability to learn from the natural world. Below are ten remarkable examples where biology has shaped modern engineering and science.
