Question

Quizplus · Accepted Answer

The presence of thermophilic members in some bacterial lineages supports the idea that life originated in hot waters near marine hydrothermal vents. These organisms are able to thrive and reproduce in high-temperature environments that would have been present at hydrothermal vents, lending credence to the idea that life may have started in these extreme environments. The other answer choices are not directly related to this hypothesis.
