How oxygen gave rise to life and a gold disc intended for extraterrestrial eyes and ears

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - New research confirms that a rise in atmospheric oxygen drove oxygenation of ancient oceans on Earth, and ultimately led to the evolution of complex animals. The study provides insight into how the Earth came to support the wide diversity of life we see today. See article.
g Life - A lost world populated by fanged frogs, grunting fish and tiny bear-like creatures has been discovered in a remote volcanic crater on the Pacific island of Papua New Guinea. See article.
g Message - A 12-inch gold plated copper disk containing recorded sounds and images representing human cultures and life on Earth — intended for extraterrestrial eyes and ears — is traveling about the galaxy. See article. Note: This article is from 1996.
g Cosmicus - A rover that has been driving across the ocean floor off the California coast is providing researchers with an entirely new view of life in the deep ocean. The Benthic Rover is exploring the unique habitats deep below the Pacific waters and is also helping document the effects of climate change on these fragile environments. See article.
g Learning - Two newspapers in Bangladesh were fooled by a made-up story in the satirical newspaper "The Onion," reporting that astronaut Neil Armstrong acknowledge that he Apollo 11 moon landing was faked. See article.
g Aftermath - Quote of the Day: “If we realize that there is other life at a higher order of multi-cellular organization of even adaptation of environment, I think that would profoundly rock our boat.” — Jim Garvin
