' Wrote:Human evolution is slow though, the Nomads just adapt again and the problem is solved.
They were designed to be this way. Originally with the purpose of living in different areas of space, and on the many planets of Sirius.
Evolution =/= changing. Cells can change individually, one of the biggest results is cancer, and that can overwhelm you in under a year.
Besides, even adaptation has a limit.
EDIT: though the progression is unlikely, and yeah, probably slow. Given the amount of people in Sirius, however, it's more than possible that someone already -is- incompatible with Nomad genetics.
