Quizplus · Accepted Answer

Scientific drilling of Eniwetok and Bikini Atolls by the U.S. government in preparation for nuclear weapons tests confirmed Darwin's hypothesis that coral atolls had a volcanic substrate underneath that formed the original platform for corals to colonize. Samples were collected from drilling and analyzed, providing evidence for the theory of subsidence and volcanic origin of atolls.
