(Sorry if this already been said)
Too all those who believe in evolution
how do you think the human can further evolve? what's left, within the realm of realism, can YOU imagine humans evolving further from what we are in this day?

Not really, but i believe it will happen, all animals adapt to there nature, like in Darwins research, turtles on one island had longer necks, and there weren't as many leaves close to the ground on that island, on a different island there heads didn't have to be as long because the majority of the plants that were on the island were closer to the ground. we will evolve, but not many will notice in what ways we're evolving.

So we cant fly without the the use of an aircraft
You think we'll grow wings?
We cant breath underwater
You think we'll develop characteristics to help us breath underwater?
Jus sayin..

not at all, we don't need to do those things to survive, why would we need to fly or breath underwater? not our niche.

Global warming, the earth is becoming hotter and hotter.
How will humans evolve to adapt to that?

they cant because global warming supposely heats the earth faster than whats natural, and to evolve for somethin that huge (extreme temperature) would take alot longer (if possiable to evolve to that at all). You should know that at certain cutoff temperatures no organisms can survive, and that's just talkin about the heat...lets not get started about flooding from the heat melting the ice caps

But the whole point of evolving would be to survive to that cutoff temperature.
isnt the whole point of evolution to adapt to things not previously able to overcome?
based on that, i'd think the cutoff temperature doesnt play a factor.

I don't really believe either side on the 'humans are n years old', mostly because I don't know how they calculate that stuff, and how they know that it is accurate...anyone able to link me to the process of finding out how old something is?

Jus sayin.. good, glad people are raising questions making me think a lil bit... but anyways, you have to adapt to situations to survive, not just to do things we can't, who knows how we will evolve, or our body will change to be able to survive global warming, perhaps our blood sells will get a high specific heat over the years, or our body temperature will raise and our organs will have more resistance against the hotter body temperatures.

Yeah I got ya en.wikipedia.org/wiki/Radioisotope_datingThat was the process mentioned previously in the other link. There are other ways of dating things as well like carbon dating and so on and so forth. Respect Reptillian

So in your belief, if global warming keeps advancing at the rate it is, the human population will cease to exist, or be drastically cut down?

so many variables with science in the factor as well, i ain't sure

Global warming dont take such a dramatic effect to wipe us out before we evolve. Think about it, since the indutrial revolution in the 1700's the earths temperature has rose about 1 or 2 degrees. So in 308 years it has rose that much. However it wont be from heat that we will be dying from, it will be the effects of heat on the eco-system. Natural disasters will occur more reguarly and more severely, water levels will rise and most coastal destinations will be submerged if we carry on like this.
But as for swimming underwater... If we were forced to live partly in the water and partly on land we would hunt for fish underwater right? As we continue to hold our breath our ability to do so for longer becomes better... As the years go by all of us would have massive lung capacities, however it would take endless years for us to become an aquatic mammal.

cs^
tho imagine it the ability to survive for hours under water in billions of years ifit happend it would be some cool shit

For that to work, it would be that the humans BORN with a predisposition to being able to hold breath under water would survive, and thus be more likely to reproduce, and more favourable to prospective partners, thus increasing the chance of the bigger lungs allele being passed on. for those who don't know what an allele is An allele is a variation of a gene, eg the gene for eye colour can be blue or black (for example) blue and black are different alleles. Eye colour is the gene. If blue eyes somehow mean we're more likely to survive longer in the heat.. more people with blue eyes will be born in the desert where it's hot, because those with brown eyes may not survive to mate, and thus there are fewer brown alleles in our gene pool to be passed on. thus in a million years all the people are blue eyed.. that's a simplified example.. also people, you're missing a crucial factor. what's the probability that we mutate: a. something useful and not harmful (fingers not retarded hoof/finger combos that do jack all) b. something useful AND helpful (longer fingers) c. this mutation being passed on.

And who's to say that any useful mutation will turn out recessive and die out through reproduction?

Not neccessarily, you dont have to be born with bigger lungs to acheive them. You can expand your own lung capacity by practising holding your breath. Im not saying because I practice holding my breath my son will have bigger lungs. Im saying that's how Humans adapt to their surroundings. Adaptation and Evolution are two different things. Im aware of that.

^Ah missunderstood you. The idea that a man who trains to have bigger muscles will pass them on to his kids is a common and somewhat logical misconception. This thread is getting good. I'ma have to +rep people in it a lot.
