I think this should not post on political mud-pit forum anyway.
en.wikipedia.org...
This is the wiki page of homo sapiens.
en.wikipedia.org...
And the page of Ursus.
There's many species and subspecies on the Ursus page ,I saw black bear and brown bear are not a same species.Because their color are different?Then why those different color of human is a same species?And if they are same species,why there's no human subspecies classify by their living area and subtle difference ?
Difficulty of defining "species" and identifying particular species
It is surprisingly difficult to define the word "species" in a way that applies to all naturally occurring organisms,15 and the debate among biologists about how to define "species" and how to identify actual species is called the species problem. Over two dozen distinct definitions of "species" are in use amongst biologists.
Most textbooks follow Ernst Mayr's definition, known as the Biological Species Concept (BSC) of a species as "groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups". It has been argued that this definition of species is not only a useful formulation, but is also a natural consequence of the effect of sexual reproduction on the dynamics of natural selection.

No, they have many different characteristics, just look at the physical description section of the pages for both species.

No,I said skin color.
en.wikipedia.org...
You mentioned dogs(Canis lupus familiaris) ,they looks really different but can breeding...so it's a same subspecies.
I feel so mess up for biology taxonomy.

Not by the skin color only ,but I prefer there's a subdivision list as subspecies of bear.

If you want to go classifying people of different colours as different species, go right ahead. Personally, I classify people of different intelligence as different species. Wannabe racists and apologists for colour prejudice, for example, I classify as a very inferior subspecies of Homo sapiens. In an ideal word, they would be prevented from breeding — and from posting rubbish on the internet.

Huh oh Candlestick....looks like the political correctness police have been alerted to your posting! Beg forgiveness or Astyanax will have you castrated. One mussn't speak of our differences, it doesn't bode well for the health of the "hive"
