There are two points of view. On a religious aspect we will all be brought back to perfection, the way God intented. Scientifically speaking, a lot could happen in 10,000 years. If Humans have apart in it we could look like anything. We would want to be healthy, strong and intelligent. Taller, slender, bigger brains. Or on the other end of the spectrum, weaker, feeble, dumber. That will happen if we let machines do everything for us. Which is what man is gunning for.....well, that's all I got.
Just like what aliens in spacecraft are reported to look like - small, pale, big eyes, poor muscle tone from flying so much and being weightless. Yep - those darn aliens might actually be us traveling back in time, lol.
We haven't changed all that much in 200,000 years so 10,000 really won't make that much of a difference. Now should we establish a large permanent colony on another world, say Mars for example things would change drastically. Mars has 1/6th of the gravity as Earth and receives about 85% as much solar energy as compared to Earth. The lack of gravity would effect our skeletal structure, our bones would become thinner and we would begin to grow tall. Our muscles would also become weaker and less pronounced, our skin would have a further reduction in melatonin making us paler. This could occur over a very short period of time on an evolutionary scale, but definitely in 10k years we would see distinct physical differences between humans and our martian cousins. Martians could have an average height of 8 or 9 feet yet weigh as little as 120 to 140 lbs. Their skin could range from a pale olive to a greyish white, hair color would most likely be unaffected. Of course this would require limited cross breeding and isolation from Earth, if we just stayed for short periods and continued going back and forth, no real long term changes would occur.
At our rate of evolution, we would all be ugly with enormous butts (most of us are already there). At our rate of behavior, we'll most likely all be dead, with the way some people are freaking out about "Obama taking their guns away". They'll shoot everyone who disagrees and eat the weak ones who survive until there's one guy left. Then he'll die.
now that we are obsessed with computers, people will be using computers for almost everything. our eyes will get bigger so we can absorb the information on the screen. we ha hair to keep us warm. it wont be necessary so all our hair will fall off.our fingers will evolve to type better unless we invent a psychic link to the computer. we will always be indoors so we will be very pale as our color goes away. scary huh? just like the aliens.
