How long have the human species (homo sapiens) been in existence? And how long do you think it's gonna be till

I can't tell you exactly how long we've been in existence, no one can. But to answer your second query with the way things are going i think we have two more generations of life left in us before total extinction due to pollution, religous wars or anarchy. Sorry, have a nice day.

Homo Sapiens Sapiens (although the "sapiens" of many humans are sometimes questionable.)

Humans won't look particularly different 5000 years from now on a natural evolutionary track, besides probably being taller and having less hair. Of course, with the advent of genetic technologies and the changing picture of the world ecosystem and available resources, one cannot say what the human race, if it remains, might look like 5000 years from now.

We did evolve from a previous species, one that diverged from an ancestor that was common to apes, but it's possible that the human line was never, strictly speaking, the SAME as an ape...it depends on how severe the genetic mutation was...\n\nddead: I like how you point out all of the hoaxes and don't state that there have been many skeletons found and recorded for Home habilis, Homo erectus, Homo neanderthalensis (while not necessarily man, still the same genus and possibly one that bred with sapiens), and you don't even mention the whole genus Australopithecus, a commonly cited group of ancestors...\n\nEvolution hasn't been proven, but there is a theory and ongoing science to support this theory, part of which is actual physical evidence...Creationists have stories and faith, but I guess that's enough for them...

According to the Population Reference Bureau, the estimated population of Homo Sapiens that has ever been born on Earth up until the year 2002 is 106,456,367,669.  \n\nThe population in the year 2002 was 6,215,000,000.  \n\nTherefore the percent of people living now compared to all that have lived is roughly 6%.  Quite high if you think about it.

Demographers have come up with estimates ranging between 69 billion and 110 billion humans.\n\n\nA complication, among scientists at least, is that we do not know precisely when our primate ancestors became human. Many researchers have arbitrarily settled on one million years ago, even though our own subset of the genus Homo, H. sapiens sapiens, did not emerge until around 40,000 years ago.\n\nIf the paleolithic crowd (1 million years to 25,000 years ago) strikes you as too crude for admission to the communion of saints, subtract 36 billion or so from the figures above.

Considering that the oldest tenuously linked ancestor "Lucy" lived a mere 3 million years ago, and all of recorded history occurred in the last 5000 or so years...you are asking what our descendents will be doing on a time scale that is over a thousand times longer than it took for us to evolve from Lucy, or over 1 million times longer than it took for us to progress from stone age to space age....

I think its 10 - 20 human years.

nothing really, since that there was earth 5 billion years b4 humans. so i guess the next 5 billion years( thats when the sun will combust) will be really qiuet!

About 2,000 years i think

There is some debate on this, but from my Archaeology class, I learned that the first real human (homo sapien) found is approximately 160,000-120,000 years old.  This skeleton was found at Klasies River Mouth, South Africa.  \n\nI hope this helps!

Homo Sapiens appeared about 100,000 years ago. Without any scienctific inteference at gene level, I suspect there won't be much difference physically, but they will hopefully be fitter and better fed at the world level, with longer and better lives as diseases are eradicated or controlled.\nHowever, if we look at the advances made since the industrial revolution and the earlier age of enlightenment, we will be talking an amazing and unpredictable future, assuming we don't wipe ourselves out. Compared to the 100,000 years we've been here, we've developed the majority of our current technology over a miniscule 300years and the increase in advanced technology culminating in electronics and computers in reality over the last 50, although obviously based on earlier work. It's a really amzing time we're living in, but hopefully the rest of the world will ultimately benefit from the globalisation of technology in a positive environmental and social way and not as is currently the norm of wanton profligate usage of natural resources of western "developed" societies and the random conflicts of the world's societies as a whole.\nMaybe in the next 10,000 years we'll grow up?

we still have about 4 billion years to go on that\n\nhttp://en.wikipedia.org/wiki/Sun

Actually, we're Homo sapiens sapiens, so before us would be Homo sapiens.

Somewhere around 4 or 5 billion years. Or if you choose the biblical version, around 6,000 years, depending on which religion you subscribe to.

Absolutely none.  "Missing Link" or "Transitional species or fossils" have not yet been found.  Homo Sapiens Sapiens (modern men) have no connection to other species, contrary to what evolutionists would like us believe.  Unfortunately, most common textbooks on biology claims that there are hundreds of transitional fossils that have been found.  These so called evidences are uncomplete and therefore, unreliable.  SOme of the fossils that have been reconstructed are actually mixed bones of various species.  The Peking Man, was found out to be a hoax, being constructed from the bones of a man with arthritis and that of a pig.

Since you are severely limiting the "domination", my answer is no. First, you are saying this species "will become", which I understand as evolving from one of the existing species in this planet. Second, you say "homo sapiens", which means the time span is not long enough for us to evolve into a different species (not necessarily smarter). At last, you also say "intelligent", which rules out the "domination" by virus, bacteria or insects, which, at the moment, seems to be the biggest threat.
