Answer 7

At the present time, there is only one: H0mo sapiens.

Answer 8

a species is a group of creatures that can reproduce fertile offspring, there fore there is but one human species.

Answer 9

Since you are speaking in present tense, the answer is one known.  It is possible that there are living remnants of Homo Floresiensis in Indonesia.  In addition, it is possible that the Almasty is a surviving Neanderthal or less likely a Homo Erectus.  Both these species lived to at least 30,000 yreas ago.  I would doubt that bigfoot or Yeti would be considered human but if they exist, who knows.  

Answer 10

Part of the issue is how you want to define "human" Would Australopithecus count? What about Homo erectus? If you are talking of the present time, there's only one human species, Homo sapiens sapiens

As one site pointed out: "Under the current taxonomy (based on genetic rather than behavioral criteria), the term "hominid" refers to members of the biological human family Hominida" Which covers our predecessors

Another site gave this:

SPECIES                                   TIME PERIOD

Ardipithicus ramidus                   5 to 4 million years ago

Australopithecus anamensis       4.2 to 3.9 million years ago

Australopithecus afarensis          4 to 2.7 million years ago

Australopithecus africanus          3 to 2 million years ago

Australopithecus robustus           2.2 to 1.6 million years ago

Homo habilis                              2.2 to 1.6 million years ago

Homo erectus                             2.0 to 0.4 million years ago

Homo sapiens archaic                 400 to 200 thousand years ago

Homo sapiens neandertalensis     200 to 30 thousand years ago

Homo sapiens sapiens                200 thousand years ago to present"

Personally I'd start "human" with Homo erectus. His was the first of us to leave Africa.

As an aside, skin color doesn't determine species or even race.As a rule of thumb a species is a group that can interbreed and produce fertile offspring. All humans can interbreed.
