A Scientific Case for Martian Panspermia: Geochemical Privilege, Asymmetric Transfer, and the Reframing of Terrestrial Abiogenesis

Abstract The origin of life on Earth has traditionally been framed as a terrestrial phenomenon, emerging from early Earth’s oceans or hydrothermal systems. However, advances in planetary science, geochemistry, and impact dynamics increasingly support an alternative hypothesis: that life may have or
