Can Humanity Thrive Beyond the Galaxy?
Sayaka WAKAYAMA, Teruhiko WAKAYAMA
Volume 71, Issue 1, Pages 10-16
Cover Story:
The expansion of humanity into space is inevitable. However, human reproduction within space habitats or on extraterrestrial planets poses profound challenges including harmful mutations caused by cosmic radiation and abnormal development of embryos and fetuses in non-terrestrial gravitational environments. Moreover, colonizing other star systems necessitates the transportation of thousands of individuals from each animal species to the target planet to prevent inbreeding-related degeneration. Looking further ahead, as humans disperse throughout the galaxy, the imperative to preserve all genetic resources from Earth permanently and securely becomes paramount. This review examines the issues that must be addressed to ensure human prosperity in space, as well as the challenges that need to be resolved for the transport and long-term preservation of vast genetic resources.
