Thousands of years ago, human domesticated wolfs and from this domestication came dogs, one of the most varied species on earth. This occurred through simple genetic manipulation and forced evolution. What this makes me wonder is if an alien civilization enslaved humanity, over thousands of years could they somehow genetically manipulate the human race into different breeds, like dogs? The features my alien species want to have choices on in their human breeds are as follows;
- Size; some aliens need tall slaves to reach thins while others need short ones for going into tight spaces, like mines.
- Muscle mass; Manual labour slaves need to be bulky, while house slaves, sex slaves, and pets need to appear non-threatening.
- Appearance; Not in the way humans differ from each other now, but instead in ways such as number of body parts such as limbs(including tails), eyes, ears, etc. For things such as circuses and other jobs that would require extra parts.
