- The Drake equation estimates intelligent alien civilizations by multiplying factors like planet formation, life emergence, and communication technology development.
- Zipf's law shows word frequency inversely proportional to rank, observed in human language, dolphin whistles, and humpback whale songs.
- Researchers use animal communication as proxies to test language theory rules before applying them to potential extraterrestrial signals.
