Study Indicates Intelligent Life Common on Earth-Like Planets

Recent research suggests that intelligent life may not be as rare as previously thought, challenging the long-held 'hard steps' theory that posits human evolution was an improbable event. A team from Pennsylvania State University argues that life could be a predictable outcome of planetary evolution, increasing the likelihood of similar life forms existing on other Earth-like planets. This shift in understanding suggests that the interplay between life and environmental conditions plays a crucial role in the development of complex life. Concurrently, the discovery of the exoplanet HD 20794 d, located within its star's habitable zone, heightens hopes for finding extraterrestrial life, as it may be capable of hosting liquid water. Moreover, a survey of scientists revealed that a significant majority believe in the existence of extraterrestrial life, with 86.6% of astrobiologists affirming the likelihood of some form of life beyond Earth. These findings collectively open new avenues for research into our origins and the potential for life elsewhere in the universe.
