no

Well, since we our only view of the universe is the Milky Way Galaxy, there's a lot out there that we don't yet have the tools to explore. I think as vast as the universe is, there's a pretty good chance that there are other advanced life forms living somewhere in the great beyond. I mean, why not? Anyway, until we're able to more fully explore the universe, we'll never know for sure.

One species and several ecotypes sharing a common genome; there has not been another race since Neanderthal and Homo floresiensis became extinct. Race is at best and artificial construct with the purpose of subjugating other cultures and justifying that subjugation.

Yes , please ! One human race is more than enough !

Yes there is only one human race. The nazis advanced the theory of multiple races based on skin color but it's flawed if not totally incorrect. It was more or less to give them the base from which to prove one race was superior to others.

No i don't believe that.

Yes - the human race.

There is one human species. Race is an artificial concept.

I think the mind labels things, so in a sense there are races. Although I agree with what everyone is saying here, I think we need to acknowledge that there is something to that feeling of connection with people "who look like me". I say this because at 35 years old, I went to a rock concert and saw an Indian man as a lead vocalist and I felt something I never felt before. I think there is something deep in our psychology that was probably very helpful to our evolution in recognizing"members of our own tribe". I think we've evolved past the importance of such things and race is basically irrelevant, but I do believe they exist. I see it like gender. I hope one day we reach a point where gender is as irrelevant as race is now, but even at that point, gender itself will still exist.

Many Anthropologists are saying there is no such thing as 'race'. There are cosmetic and cultural difference but we are all one species. I have heard there is a wider genetic difference between Chimps living in open fields as those living in woodlands as between any human groups. To me race is a term used to justify discrimination (kind of like 'homosexuality' or 'atheist'.

Yes BUT. We are one "race" or species just as is our domestic dog. A poodle is the same animal as a Great Dane, but they have differences because of selective breeding. We do not selectively breed humans, but some groups are isolated from others and have traits that are fairly unique to that population. Some humans have more neanderthal blood, while others have genes from around the world. Given the movement of humans throughout our history and the mix of genes, there is no even generalize about many traits. While it is true that that people who live in the mountains of Tibet have a genetic adaptation to live in that region, it says nothing about their humanity. In other words, the mix of genes which have caused physical differences and adaptations have not separated us into different species. We are all thinking feeling beings, who share the same desires and instincts, all having the same potential. The huge differences we see in behavior around the world is caused by culture, not by of skin color or other physical traits. We are one race.

I agree Michael, human is a race.

Yes.

Of course, there's only one.
