It’s fun to think that maybe these are the next probable steps in the evolutionary process. Space travel is the next step in human evolution. We have already mastered our domain here on earth, what follows may be the necessary genetic modifications required to endure venturing forth. Lack of gravity makes our bones weak so maybe we will grow taller to offset the effects. It’s hard to tell what biological processes are necessary to prepare the next generation for the future. Great post, thanks for sharing!
