Whats sad in all this is that evolution has yet to be proven. It certainly seems like it exist but up untill this point no scientific evidence has been provided to argue that evolution in fact exists. Now keeping that out of the way, if we are to evolve it probably wouldnt be very good. We would most likely get more fragile as we condition ourselves to cushy living. Our ability to think might become broadened but were basing this on the assumption that our society will exist long enough to bear the fruits of evolution. Were done with oil in 50 years and we could easily see a nuclear event occuring that kills us before then. It would at least take 5000 years to lose something like a pinky toe and thats provided we live in 5000 years of peace.
Wasn't Darwin's theory of natural selection proof that evolution does happen? It's the need to adapt to the environment that causes evolution. Simply put, the ones who can't survive due to some inadquacy die off (for example, if there was a need for strength to survive, the weak would die and drop out of the gene pool and the strong would continue to mate, making a population of people stronger than before). You can't say that hasn't happened before to some species somewhere.

I was studing for my biology test when i got this weird tought:
Different species evolve together with environment. I mean if environment runs through serious changes, iceage etc. then some species will die and some new will evolve. This is all set with how capable are some species able to evole and how connected are they with environment.
Now, human is smart. We can avoid environment changes. If its cold, we go inside and turn oure heater on or something. You get the point. But if we can avoid environment, will we develope further? will we be next millenium 2 feet taller and with three hands or what? will oure brain only develop? will we die because we cant develop further? etc. Gimme some answers
I believe that the human instinct would continue to react to the heat senses. So if its cold we'll continue going inside. Now when you talk about 3 hands or 2 feet taller, that might be taking it a bit too far because its not how we adapt or evolve. Maybe instead of growing more limbs or body visual body parts, our muscles or brains could escalade to a point where we can jump/ run or think at supernatural standards.
Well if the scientists prediction of a major new iceage is correct, then we wont be able to survive it because it will be so extreem that our buildings will probably not be able withstand it.
This of course will be over a large period of time, and at first we could maybe survive, but eventualy things like farming will becom impossible and a large number of animals will die. without food, the human race is doomed.~this is just a theory~
Other theorys include: we revert back to primitive bings, we evolve into even smarter beings (large forhead, etc...), or somhow the human race will die out because of either disies or infertility problems (which is on the rise).
.....on the other hand aliens could come and use us as lab mice and create a bunch of super mutent humans....but that si unlikely~^_^
all in all, i think it is impossible to actualy know what we will turn out like in the future.
I'm afraid. Hopefully we'll be able to colonize new planets before that.
I really also have been wondering about humans evolving, since we don't really have much to deal with. I mean, we're losing hair!We can't adapt to the cold as easily anymore!

Ok natural selection and evolution are two different things. Darwin was a fan of both. Im not saying i disagree with either of these theorys and to me it doesnt matter if evolution exists or not. My point is simply that evolution is the fundamental change of a speciel even if its really small. So far they havnt been able to prove that a species has been altered.

let's just this: if at any given moment we start to colonize the moon and space, and newtypes start to appear, then yes, evolution proves its here
um the chances of this are nonexistant. Its been proposed that humans in space would evolve but as i said earlier it would take thousands of years _________________ "Let them hate, so long as they fear"

Evolution is happening.....There is plenty of evidence that suggests its existence.......Like how viruses become immune to certain drugs all the time.
Say which do you guys think is more highly evolved? The Chimpanzee or the human being? _________________ [img:309:200:9b3695521e]http://img69.imageshack.us/img69/8583/dobedobedojs0.jpg[/img:9b3695521e]

Neither is "more" evolved...
Just as humans aren't any more evolved than some single cell protozoa.
Just because something is simple, doesn't mean they're less evolved.
If conditions and requirements for survival allows, we humans may evolve to some lowly creatures as we once were.
Because nothing evolves just for the heck of it. It's all give and take. If being smart is so great, why do other animals not have huge brains like ours? Because developing and maintaining those highly metabolically active nerve cells is very costly. If they can survive and reproduce successfully without being smart, they won't evolve big brains.
In fact, many of the simplest of structures are often the best. It's all about efficiency.
By the way, if someone still thinks evolution has not been proven yet, they just don't know or doesnt want to know about evolution.
It's pretty much accepted that things evolve all the time.
Even in ancient times, humans knew that animals change in shapes and behaviour by looking at domasticated animals. Although domestication is a artificial selection and not natural selection, there is no difference. Evolution is evolution whether humans caused it or occured naturally.
Actually species evolve by influence each other all the time.
Do you know why beetles have so many species compared to other families of insects? It's because they're many of the plant's pollinators, they evolved and specialize on certain flowers. The flowers and beetles "coevolved".
Evolution has also been witnessed many times already, probably the galapagos island finches are the best example. Go read about those finches if you want to know.
Oops looks like I've been blabbering about this stuff too long...
That's what i get for being in bio major... _________________ [IMG:258:200]http://img.photobucket.com/albums/v435/ypark/sigs/3fsn.png[/img]

Heh.....You're pretty smart.....Finally!! Someone who takes my posts seriously!!!
And you're right....Theres no way to tell which is more highly evolved...Because evolution doesn't simply happen all the time and it's not only in one direction.
But I have to disagree with you......I think that all bacteria are more highly evolved than human beings.... And I'm not gonna explain myself because I'm unreasonable and lazy.
Off topic: Really kindof changes your outlook on life to learn that humans arent the most successful species as we liken ourselves to be doesn't it?
I really need to stop reading science books.........Seriously........Damn you Stephen Jay Gould........ Has anybody else read books by this author? Hmm.....I'm a nerd... _________________ [img:309:200:9b3695521e]http://img69.imageshack.us/img69/8583/dobedobedojs0.jpg[/img:9b3695521e]

just so random points perhaps to correct some misconceptions that i've read here from some ppl and to provoke further thoughts.
survival of the fittest does not mean the survival of the strongest. fitness means the ability to pass on ur genes. u can be weak but loaded with tons of $ and attract the gals to bear ur children. in that case, u are fit.
since food was hard to come by in society before mass production and industrialization occured, humans have naturally evolved into beings that are extremely good at storing fat (so it can be used as a back up energy source when food runs out). this occured via natural selection, where those with problems storing fat, naturally werent able to survive as well and pass on their genes when food became hard to find. but of course, in the world today, food is easily obtained, yet our genes remain the same in terms of the efficiency to store fat. As a result, this is one reason why there is such an obesity epidemic in the world today, and why diabetes and CVD are on the rise.
it is not hard to see that ppl with health problems related to fat (pretty much all the top killers) are more likely to die and not pass on their genes (especially as the age of getting them keeps getting younger) so eventually, evolution will work so that the human race in the future will be one that possess genes not as efficient at storing fat as we are today.
evolution is very real, and i find it amusing how the debate of evolution vs creationist (and also intelligenet design) in high school is back again.... i say this.... go ahead and teach only creationist theory and believe that the world only formed a few thousand years ago.... and have all your students FAIL IN UNIVERSITY bio, history and geography.

I don't really think humans will evolve at all from now on.......Too much mixing of blood....Too much interconnectivity......Evolution works best when two groups seperate from each other. Slight changes maybe but nothing drastically different _________________ [img:309:200:9b3695521e]http://img69.imageshack.us/img69/8583/dobedobedojs0.jpg[/img:9b3695521e]
I don't really think humans will evolve that much anymore... The advancement of technology will cover for any large environmental changes, and as pyrorecca said, too much mixing of blood.
humans will probably hange with the enviroment we ourselves have created, eg less physical work could result in smaller bodies and muscels over time. other than these farfetched ideas i don't think the human race will change that much because we can control the enviroment. _________________ [img:350:100:b9d927e767]http://i4.photobucket.com/albums/y104/tehalbino/gaara2.png[/img:b9d927e767]

Ahh..Because Viruses are TOO highly evolved to be living organisms!!!
Think about it: What would be the last living creature if the apocalypse came?
Viruses!!! Why? Because they aren't alive to begin with!!! Makes complete sense
Go Pyro!!! The dude with an IQ of 168!!!! _________________ [img:309:200:9b3695521e]http://img69.imageshack.us/img69/8583/dobedobedojs0.jpg[/img:9b3695521e]
what about cockroaches and twinky's, i bet they could survive the apocalypse. _________________ [img:350:100:b9d927e767]http://i4.photobucket.com/albums/y104/tehalbino/gaara2.png[/img:b9d927e767]
