Horseshoe crabs are unmistakable: they look almost like dark brown hubcaps and move like army tanks. Their name comes from their shape, which is similar to a horse’s hoof. Horseshoe crabs are prehistoric: they have not changed much in over 400 million years, almost 200 million years before the first dinosaurs. What could this ancient species have to do with the rush to create a vaccine for Covid-19? Everything.
