The emergence, evolution, and survival mechanisms of microorganisms in extreme terrestrial and hypothetical extraterrestrial ecosystems will be discussed by leading scientists from around the world during the first meeting of the Microbial World Network (MWN) on September 6th and 7th, 2023. During the first day, our topics will focus on the origin of microbial life, its organisation into microbial communities and its subsequent evolution. On the second day, we will cover the extreme habitats of terrestrial microorganisms, the potential for their survival and hypothetical extraterrestrial microbial systems. The main purpose of the meeting is to identify the most pressing issues regarding the microbial world and examine topics for discussion in future international meetings to be organised by MWN.
