Quote - the theory that we evolved from a single homo-erectus species says that we went from Homo Erectus to highly varied Homo-Sapien in under 2 million years. The Diversity of the Canine species took 10 million years to get to today from thier single ancenstor.  How did we evolve so monumentally fast?

To Sam, have we ever been so kind to our slave workers?

There is a species of crab, native to Japan, some of which have shells with markings remarkably like a samurai.  That tendency is now present in the majority of these crabs but only came about in a few hundred years.  

There's a moth, native to the UK, which had black and white markings.  The ones with primarily black markings became dominant during the industrial revolution, since they were harder to spot amongst all the soot - streaked buildings.  Since then, with the advent of "clean air", the mainly white ones made a huge comeback.  Again, all in a very short space of time.

My point is, give a species enough space to roam and they will find niches and begin to specialize.  Dogs weren't left to their own devices; if anything, we may have slowed   their diversity.  Until recently, due to all the interest in pedigree and pet breeding.

As for us, there's no real need for any kind of diversity.  Even the little we got is pretty useless by most standards.

Assuming a highly advanced civilization would need a slave population, I think it's reasonable they would tailor our DNA to be more disease resistant.  Keep the slaves healthier for longer, get more work out of 'em.  Perhaps our slave owning ancestors weren't bright enough to figure that one out but I'd put good money on an alien super species to think of it.

Another thing, why is chimp DNA so close to ours, and their blood DNA identical?  Does that mean the aliens experimented on them, too?
