Why are there not more "types" of humans?

[MisterJackson]

I'm sure there's some blindingly stupid answer and that I'm the only person to not know this answer, but why are there not more variations in the human race.

It's pretty amazing if you think about the variety of dogs on earth (a PBS special on this subject caught my attention awhile back).

So what has caused the human race to split into only a handful of "races" and not more distinct "sub-races"?

Can you imagine a world where we have 100 different races?

Or am I just being retarded this morning.......

 

[mercanucaribe]

Dogs were bred by humans into all those races. There is only one natural race of dog- wolves. Wolves are all the same species, the same species as domestic dogs, and can all interbreed. Foxes may be too, but I'm not sure. All modern domestic dogs came from wolf ancestors.


Edit: I don't know why I said there's only one race of dog naturally.. there are different kinds of wolves.

 

[eLiTeGoodGuy]

Technically I would say we have different "sub-races". Not just looking at race (black, white, latin, asian, etc...) Sure we all may look the same but would you group people from Texas with People from New York. They each have a different style of living and to go with that a different way to behave. So I guess I am classifying a culture as a race.

I'd imagine that a higher-intelligence could classify us by different "sub-species" but I'd guess the reason we don't is because it's a VERY touchy issue.

You don't have selective breeding with humans that's why. Dog breeders can cull the offspring that don't have the qualities they are looking for, and have a much shorter lifespan / lifecycle. So changes on dogs over time would occur much faster.

If there were someone who could cull the humans that didn't match their ideal, then you would see different types of humans, but that is illegal and as such doesn't happen. If you wanted to make a brand new race of humans it would probably take in the area of several thousand years of selective breeding.

Slave owners did breed their slaves for certain traits, according to Dave Chapelle.

 

[leftyman]

from wiki

As humans migrated around the planet a variety of dog forms migrated with them. The agricultural revolution and subsequent urban revolution led to an increase in the dog population and a demand for specialization. These circumstances would provide the opportunity for selective breeding to create specialized working dogs and pets.






Humans evolved naturally.

But that was for a much shorter period of time, and likely not as dramatic. Dog breeders will often inbreed to enahance a specific trait, and then introduce new bloodlines for general healthiness. Most of the clearly defined breeds have a very long history of breeding.

 

[torpid]

Well we have races which do have some genetic differences, such as the while BO thing in some koreans and japanese. But overall I'm thankful we aren't all purebred humans because I would hate to be genetically predisposed to major physical ailments like many purebred animals are.

 

[SpecialEd]

I read in Time magazine that something like 90% of human genetic variation is found in Africa. Africa does have the pygmy tribes which exhibit noticable physical difference.

 

[Atheus]

But there _are_ 'subraces' of humans - they may not be as different from each other as dogs, but they definitely exist. For example someone might be classified as 'white people' but you can tell if they are Italian, Eastern European, Scandinavian, etc etc.

Also according to Jimmy the Greek but he got fired for saying it.

Or we found it necessary to breed with them... ultimately therefore, making everyone the same..

That would explain the weird fetishes that people have ;-)

Canidae is the family of animal that all dogs originate from, there are many genera (plural genus) and species within the family canidae. Kingdom -> Phylum -> Class -> Order -> Family -> Genus -> Species is our current method of life classification and dogs fit in, under the last two with a family of Canidae.

Most dogs and wolves are generally genus "Canis" and most foxes are genus "Vulpis" but there are many others.

http://en.wikipedia.org/wiki/Canidae






To answer the OP's question it is because there are many genus and species of dog whereas humans are all specifically homo sapiens. Any variation within humans can be compared to the variation within all border collies.

 

[Zysoclaplem]

When you think of dogs, cats, birds, fish, and humans, each species shares certain features.
Dogs have four legs, sharp teeth, large ears, tails.
Fish have fins, gills, tails.
Cats four legs, sharp teeth, pointy ears...
Birds have wings, talons, beaks..etc..etc..
Humans have two legs, two arms, thumbs..etc..etc..
The only real difference between animals of the same species is usually color and diet.
There are always variations that in another time might mean death.
Like hairless cats. They could never survive in the winter. Flightless birds would never survive in certain parts of the world.
Humans are short, tall, blonde, brunette, fat, skinny, black, white..etc..etc..
The differences are usually due to environment.
We all share some features, but other than that, we are completely different creatures.
But, just like some cats and dogs are born with stubby tails, some humans are born with mutations too.

If you think about it, humans, apes, and monkeys are all classified as primates. We are just a more evolved version of them.

 

[DeadByDawn]

The same thing could be done with humans as dogs given enough time with selective breeding.

and keep in mind there is a new generation of dogs every 4-8 years (roughly), while a new generation of humans comes along every 25-35 years, so it reasons that evolution in dogs is quicker.

cept you can breed a terrier with a german shepard.
not sure about chimpy human

artificial selection FTW.
