Researchers have found that many species of tarantulas have independently evolved the ability to grow blue hair using nanostructures in their exoskeletons, rather than pigments. The study is the first to show that individual species evolved separately to make the same shade of a non-iridescent color, one that doesn't change when viewed at different angles.
