Darwin, Smarwin! Why take chances.
Description
In the past couple of centuries, our colonies have begun finding minor, but growing, differences at the genetic level. It has been speculated that within a millennium, there could be significant genetic differences between the citizens of two different planets.
To help alleviate this problem we have developed a technology to control Evolution, to a degree. While adapting to one's native environment is important, certain random traits can be eliminated, slowing the diverging evolutionary paths. Each citizen will have the option to use this program and keep their genetic line from diverging from that of humans on other colonies.
For example, on the continent of Novaria (on one of our colonies), the number of children being born without any body hair on the arms and legs is 25% higher than anywhere else in our civilization. Other diverging differences include ear size, toe usability, nose size, etc.
