after millions and millions of years,is human species gonna be extinct?

As much as humans think that they're invincible,there is no doubt that one day we will be extinct. if not in next million years, the sun is going to expand in the next couple of billio n years, and the earth will become far to hot to live on.

I think it's very likely there is. Whether it's intellient, primitive or a little of both, I'm not sure. But if they are intelligent and they don't know we're here, they will eventually. We've been sending out radio waves for at least a hundred years and they've been travelling out into space since then. But when you consider the vastness of space they haven't gone very far. So I'd say it would be millions maybe billions before there's any contact because of the great distances and messages at this point can't go any faster than the speed of light. But millions of years from now, assuming humanity makes it that far, we'll be living on another solar system because by that time our sun will have died and we'll need another place to live. Who knows where that'll be and how such a mass transport will be organized. Maybe at that point space travel will be as common as driving to the grocery store. Or maybe it'll be a privilege only enjoyed by the rich. Who knows where we're headed. Anyway, that's what I think.

Yes but it will be a long time away. In 6 to 7 billion years, stellar evolution theory predicts our sun will evolve into a red giant  and will probably completely surround the Earth. I don't think I will be around then.

Memorably, a few dozen. Taxonomically, trillions upon trillions. 99.99999% of all the species ever on Earth are now extinct.

Not for another 1000 years, unless it all comes to an end in 2012

Not sure on that one.  Evolutionists say man must continue to evolve as we have over the years.  And when the secret of the 'aging' gene is discovered, maybe natural death will be a thing of the past, who knows...\n\nBut I don't subscribe to any of that.

It is very questionable that humans are evolving, at least in terms of largescale selections.  Where we are today with technology, rather than nature selecting the most fit of us, oftentimes we alter nature to allow everyone to live.  This obviously isnt true in all cases, but we are at least tampering and slowing down human evolution

Species do not evolve, individuals show variation and sometimes that variation is pro reproductive, (not necessarily pro long and happy life)  In that case a pool of individuals with that trait grows and reinforces it.  Such variation tends to be absorbed in a large mobile population and cause no long term divergence, so our own mobility and global success works against a new variety of human emerging.  \n\nOne can anticipate however that our science will progress far faster then any normal evolution and in a short time a group of therapies will be available that will offer longer life, greater vitality and sexual enjoyment, improved health in general and whatever appearance is desired.  The trend to these things already exists.  The factor that will isolate this group of advantaged humans may already exist as well, since it is likely that such biological tinkering will be available only to those who can afford it.  We may see the very rich diverging as a virtual new type of human in the next fifty years, followed by the middle class in places like America.  The difference in lifespan between a wealthy nation and a third world one is now twenty five years or more, it may stretch to a century.  A pretty big issue putting wealth and experience against endless numbers...

I hope that in 5 billion years. We have somewhat evolved beyond this planet. Besides we won't have enough land or fossil fuels to last the next five hundred. I can hardly imagine five billion years from now.

Is this what cloning basically is? Asexual reproduction? And are we headed toward making a "perfect" species?  \n*** does this mean humans will become extinct in the not too distant future?

well its not a very long span of time so there will be very very minute changes.. if we remain alive, then i think some of the changes can be:\n1) average height will reduce\n2) we will develop some adaptations in our skin, lungs and eyes to protect ourselves from pollution\nand many other possible changes...\nwe must not say that we wont be alive after 20000 years.... always hope for the best........\nLETS MAKE THIS WORLD A BETTER PLACE TO LIVE

Probably not.  Though I've lost the reference, I remember reading once that large animals (wolves, saber-toothed tigers, mammoths, etc.) would only have to get stuck and die together once a decade to produce the number of bones that have been found there.

i doubt it... the human race will also be evolving, which means that even though there might be a large current race, there will be several mutations from the norm

1) Earth: It depends on how many billion years. The Sun will evolve into a red giant in 5 billion years, swallowing Mercury, Venus, Earth and Mars.\n\n2) Humans: no. Homo sapiens will either have evolved (naturally or artificially) to another species, or destroyed itself, before the first billion years.

humans just hav only 500 yeras more bcaz the polarcaps r melting and it may caz a global warming and will distroy then whole human life..so human wont b ther 2 look like something after 1000 years...

Assuming that humans don't destroy the world...which is a pretty BIG assumption, I think maybe in a few thousand years the Earth's magnetic field may weaken to the point where it no longer deflects the harmful radiation from the sun and all life as we know it on this planet will cease to exist, and Earth will become very Mars-like...a very thin atmosphere and no surface water. But hey, that's just me.

Brian is right, but I have to add a smart-ass remark that sun will burn up and go out in a few million years, but by then the humankind will either destroy itself, or find a way to move on to other stars.
