GT. there is one major point that you and everyone keeps forgetting. If we ever do develope intersteller travel, we still take ourselves with us.
Thus, in the future, it is highly likely that some human will see an alien spacecraft, make the statement, "It looks hostile, let's fuck with it."
And the aliens proceed to exterminate the human race.
Or, if there is an intelligent race observing us now, I will almost certianly bet that as soon as it even looks like we are about to venture out to the stars, we gonna get blasted back to the stoneage, unless we change our outlook.
Another point to be made, the only way to get a colony to actually grow in population with any certianty is in a polygomist society. Approximately one male to every 10 females. This will allow for genetic diversity as well as insuring that a large number of children are born in the soonest possible time frame.
Within this system, it would be in the best interest of the colonists to actually work on desired traits in offspring. While this sounds like eugenics, and plans for a master race, it is quite the opposite. Intelligence, physical strength, dexterity, intuition would be the primary tracts needed in an off world colony.
As in the Dune Series by Frank Herbert, once a credible genetic lines with the desired traits are created, breeding back to the parent line every few generations would only strengthen the traits, eventually making them dominent.
Each colony would actually be creating new genetic branches of the human genetic tree. In essence creating sub species within the human race that are adapted for different climates, gravity, etc.
