Cicada - Wikipedia — The cicadas are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, Tettigarctidae, with two species in Australia, and Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed.

Silurian hypothesis - Wikipedia — The Silurian hypothesis is a thought experiment which assesses modern science's ability to detect evidence of a prior advanced civilization, perhaps several million years ago. In a 2018 paper, Adam Frank, an astrophysicist at the University of Rochester, and Gavin Schmidt, director of the Goddard Institute for Space Studies, imagined an advanced civilization before humans and pondered whether it would "be possible to detect an industrial civilization in the geological record". They wrote, "While we strongly doubt that any previous industrial civilization existed before our own, asking the question in a formal way that articulates explicitly what evidence for such a civilization might look like raises its own useful questions related both to astrobiology and to Anthropocene studies." The term "Silurian hypothesis" was inspired by the fictional species called the Silurians from the British television series Doctor Who.
