This essay is much in need of good editing. The ideas are solid, but as a whole, it is, in spelling, grammar, and syntax, a bit juvenile.

One very strange consequence would be that with this gene therapy, individuals could switch from being one species to the other (earth human to mars human). | |

Unless you have some reason that the first carrier of the mutation somehow fathered a disproportional huge percentage of the children; and now it just sounds like someone's badly written pornographic story :P Give it a thousand or 2 thousand years it's plausible. | |
| Jul 30, 2015 at 0:37 | comment | added | Thucydides | The near extinction scenario is probably the most likely, especially if there is some event that stops space travel and the Martians (already starting from a small base population) suffer from technological failures of their infrastructure, bring ing them down to a "genetic bottleneck" where only a few individuals become the ancestors of everyone else. Humans apparently went through this, and all cheetahs are virtually cousins because of a severe bottleneck sometime in their past. I think 500 hers might still be too short a time span, however. | |
