Question

Why didn't humans ever evolve into distinct subspecies or races?

Answer 1

They did.  A subspecies is still a member of the same species as another subspecies.  For whatever reason different races evolved in Asia, Africa, and Europe.

Answer 2

Because we never evolved into some thing. God Created us.

Answer 3

Humans evolved over a very long period of time from a common ancestor.  It would probably take billions of years for us to evolve into a subspecies, but the likelihood of that ever happening is very remote.

Answer 4

Where have you been.  Are humans not subject to the same rules that are applied to all other life?  Am I not a sub-species of my ancesters who where quite violent?  I am certainly that.

Answer 5

"Races" are not a biological construct consistent with evolutionary theory, i.e. they are arbitrary designations.  Evolution will take place on a long time frame and further selective pressures will eventuallly result in certain allelic advantages, ergo a new species.

Answer 6

We're still a fairly young species, so we haven't really had time to diverge into separate species. Not only that, but in the modern world, isolation isn't really possible anymore. However, if groups of people had remained isolated from each other, we'd probably eventually evolve into different species.

Answer 7

Your question shows a clear evidence that the ET have introduced and created HUMAN on this planet by using existing primate genes and are closely monitoring our evolution. It is the same scenario you see in many labs; they play with genes, create new virus (being) and watch/monitor how the virus (evolve) spread, cope, adapt and survive within the environment.

The problem is this:

-Most of our scientists are too busy studying and replicating what already exist in nature it is forbiden to them to investigate the ET presence or else they don’t get paid.

-On the other hand, those who believe in creationism most of them are trapped and struggling to following dogmatic sacred scripture written by the same ET, and are mistakenly worshipping the ET as God, Lord, Angel and demons.

The rest of us is free to think to do what ever they want as long as we are obedient and serve our bosses (ET) in accomplishing the task.

Basically we are a unique virus species called human with a “fractal mind”, introduced on this planet to fulfil a hidden agenda. Of course this is my opinion, no offences to anyone.

Answer 8

Why would we? We seem to be pretty well-adapted, when you include technology, to every environment on the planet.

Besides, since being the species we are, there hasn't been a lot of time.

Maybe if you'd explained what, exactly, you're thinking and why, we could clear things up for you.

There ARE a few geographical variations -- but they aren't enough for us to not be able to inter-breed.
