Many researchers assume the first life on Earth evolved in hot springs. A new study provides insights into how one type of extremophile microbe may have moved from hot springs to conquer more moderate environments across the globe. The first-ever analysis of DNA of one ammonia-oxidizing hot-spring microbe living today reveals that evolution of the necessary adaptations may have been helped by highly mobile genetic elements and DNA exchange with a variety of other organisms.

Extremophiles -- hardy organisms living in places that would kill most life on Earth -- provide fascinating insights into evolution, metabolism and even possible extraterrestrial life. A new study provides insights into how one type of extremophile, a heat-loving microbe that uses ammonia for energy production, may have been able to make the transition from hot springs to more moderate environments across the globe. The first-ever analysis of DNA of a contemporary heat-loving, ammonia-oxidizing organism, published in open-access journal Frontiers in Microbiology, reveals that evolution of the necessary adaptations may have been helped by highly mobile genetic elements and DNA exchange with a variety of other organisms.

I believe it is likely that extremophiles able to withstand the vacuum of space arrived via meteorites, and seeded the earth with life.
