Virgle: What?

So Google and Virgin Mobile have joined forces to put humans on Mars... good luck with that, guys. Especially considering how you're suggesting that all the colonists breed with one another "for the good of the colony." HA! Space Station Arkansas is what you're gonna get with that logic. Allow me to illustrate my point.

Say you have five healthy couples- A, B, C, D, and E. They each have several kids- we'll assume for now that the gender logistics work out just fine.

Their kids come of breeding age, and result in:

AB, AC, AD, AE; BC, BD, BE; CD, CE; DE

From here, it goes downhill. In order to avoid inbreeding, we get:

ABCD, ABDE, ACDE; BCDE, BECD.

At that point, we're screwed, courtesy of Google.

Two cents from a confused BrainBox.
