The question of where life originated has been contentious for a very long time. Scientists have invoked many environments to address this question. Often, we find ourselves beholden to a location, especially if we think life originated once and then evolved into the myriad forms we now know today. In this brief commentary, we wish to lay out the following understanding: hydrothermal environments are energetically robust locations for the origins and early evolution of life as we know it. Two environments typify hydrothermal conditions, hydrothermal fields on dry land and submarine hydrothermal vents. If life originated only once, then we must choose between these two environments; however, there is no reason to assume life emerged only once. We conclude with the idea that rather than having an “either or” mind set about the origin of life a “yes and” mind set might be a better paradigm with which to problem solve within this field. Finally, we shall discuss further research with regards to both environments. View Full-Text
