- Viruses represent a deep reservoir of unsequenced genetic diversity, and are almost entirely unrelated to the rest of life on earth. Some propose extraterrestrial origins, but they're only ambiguously alive - and so might not support a panspermia hypothesis for origin of life. https://demystifyingscience.com/blog/2020/3/20/originofviruses 3 comments science
