We’ve uplifted so many different races since figuring out the gengineering required.  Some like cats and dogs go everywhere we go.  Others are rare, or stay away from the rest of us.  You see, despite what a lot of people say we’re not all the same.  You can give an eagle human level intelligence and an ability to speak our words, but he’ll still want to fly away from it all and live on top of a tree, mountain, or tower.  We just want different lives.
