An American astronomer discovers a possible new design feature that would explain how Earth received the elements it needed for the eventual support of advanced life. He found isotope ratio evidence that a metal-poor dwarf galaxy merged with the Milky Way at the same time that the solar nebula was forming. The size and composition of the dwarf galaxy and the timing and location of its merger with the Milky Way are features that would need to be fine-tuned.
