Why are humans classified as one species but not different species like different species of dogs?

question

According to scientists if you are able to give birth with someone they are the same species as you. But Wolfs and dogs can interbreed but people don't call wolfs dogs and dogs wolf. Blacks, Whites, Asian etc can all mix with each other but they are all considered human. But wolfs are not considered dogs but different people's. Birds that look different are considered 'closely related' but humans that look different are considered to still be human and not just that they are closely related but that they descend from each other.

I saw different versions of this type of racism on stormfront so I just put them all together I'm not a scientist so I don't know why scientist classify some group as different species And some group as the same species/kind does anyone have an answer to this

Hmm, perhaps you're looking at this too closely.
Try thinking of it as a black dogs and white dogs, as they're not different species

I think they classify them more by what's in their genes? but I do understand what your question is, I asked my teacher this question ages ago and it took her about 2 hours to explain it to me,( she dedicated 2 hours of afterschool to me :>) So I think you should ask a teacher or someone who might know about this, you would only understand this verbally, well for me it worked...

Because we are humans!

Dogs are all one subspecies, Canis lupus familiaris.
The crown Canis lupus is the gray wolf.

But dogs and gray wolfs ARE the same species. They are both Canis lupus. Dogs are a sub-species: Canis lupus familiaris, wolfs are just Canis lupus.

I don't blame you for not understanding what a species is; most biologists don't. All too many cling to the genetic species concept, which is quite useless for most animals, the ones that reproduce asexually and the ones known only as fossils. That's why you get brainwashed kids claiming that dogs, wolves, and coyotes are all the same species because they can interbreed to produce fertile offspring. It gets even more confusing when you point out that minnows of different genera can be perfectly interfertile. I much prefer C. Tate Regan's definition, "A species is what a competent taxonomist working with the group says is a species." It sounds trite but it works and it is what taxonomists (as opposed to geneticists playing in taxonomy) use.

we are. we are classified by race though instead of type like dogs

They are all sub-varieties of the same species.

Canis lupus lupus (Gray Wolf)
Canis lupus famliaris (domestic dog)
Canis lupus familiaris, sub. var. German shepherd
Canis lupus familiaris sub var Mixed
