An old cliché has the highly evolved humans of the future sporting large heads to hold their advanced enlarged brains, "but that's nonsense, whole nonsense," said paleontologist Peter Ward at the University of Washington at Seattle, author of "Future Evolution."
"If you've ever gone through a childbirth or witnessed one," Ward says, "we're already anatomically right on the edge of how big our heads can go — our big brains have already caused extreme problems in childbirth, and if we had bigger and bigger brains, that'd cause more mothers to die in childbirth, so evolution would select against that."
Another idea, suggested by evolutionary theorist Oliver Curry of the London School of Economics, seems like a retread of ideas from science fiction writer H.G. Well's classic "The Time Machine," with the human species split in two over time — an underclass of dim-witted, short goblins, and a genetic upper class of tall, slim, healthy, attractive, intelligent and creative superhumans that eventually are spoiled by technology that will do everything for them, resembling domesticated animals.
"That's crap," Ward said. "Why would that happen? Are we like blind cavefish? After we get Google, do we get stupider? Intelligence is coded on too many genes to just lose a trait like intelligence. That's not going to happen."
Ward suggests that, if left untouched, humans might converge in appearance as populations mix. "I kind of view us all as eventually having chocolate-covered hair and medium stature, getting rid of all extremes," he speculated. "Of course, the big elephant in the room, the change from the past that you cannot ignore when talking about the future of human evolution, is genetic engineering."
Humanity now has an unparalleled means by which to direct our evolution — genetic engineering. By using viruses and other techniques, we can in theory modify our genomes, and over time, scientists may uncover genes underlying intelligence, health, athletic prowess, longevity and other desirable traits, engineering what might seem like superhuman progeny. Genetic engineering is how Ward speculated new species of humans might emerge.
"I think taboos would arise which would prevent mating between populations — 'I don't want them anymore' or 'We want natural people,'" he said. "Of course this is all pure speculation, but this is the only way I can see new human species emerging — unless we get off the planet."

So much to think about...where do you think evolution will go? What does the future hold for humans?

What about C-section babies? There is less trauma the brain but there is no supportable evidence that they are any smarter.

I say were all gonna get less intelligent. if you look at the data poor people are having more children. and it would be a massive generalization to say poor people arent as smart, but intelligence definitely plays a part in your class.

I think something along the lines of transformers isn't out of the question.

If anyone like science fiction, you should check out two books by Greg Bear called Darwin's radio and Darwin's Children. He presents the idea that humans will develop a more conscious sensitivity to human pheromones, rendering people nearly telepathic by interpreting one's conscious state through smell, esepecially ones generated behind the ear. I think he brings up an interesting point in these two books that humans will find more efficient forms of communication. I doubt this will come to fruition, but they make for a very good read.

Genetic engineering essentially means our evolution will go however we want it to, but its fun to think what would happen without it.
We know our evolution, selected our ancestors for high general learning capacity and longer lifespans. People in hunter gatherer societies are still under those ancient selection pressures so we can expect them to go further in that direction; more longevity and intelligence. Developing into a minority of exaggerated humans with naturally long lifespans and a high general IQ that suits learning a huge number of skills over a long period of time.
We in the larger part of civilization are no longer being selected for longevity; a person with the genes for vulnerability to diabetes, heart problems and Early Alzheimer's will probably have as many or more children than an individual with genes that would allow them to live to 122. We also seem to be sexually selecting for more abstract specialized cognitive skills. So the majority of us might start to break off into cognitive castes (Like Moties), being born with a huge aptitude for some aspect of mathematical, geometric or contextual reasoning. Which means parentage would determine which skills you'd be able to acquire in life, but you'd be able to acquire fantastic expertise in your field with little effort.
What would you choose? A long life where you can sample everything or a short one where you're excellent at everything you try?

Mankind won't evolve, because in the future mankind won't be man anymore.
At least, that's what I hope happens. Because it's pretty clear that these meaty shells are the cause of most of our woes. Sign me up as soon as we figure out how cybernetics work.

Ward is naive and is trying to forward his own agenda. We're already selecting for splits in the population. Apart from the genetic fact that divisions of race do not exist, have you taken a look at who's eating in the expensive restaurants on Sunset Strip and who's working in the kitchen? How tall is the CEO and how short is the janitor? When was the last time we had a President under 6 foot tall? The darker and shorter, the more likely you'll be a menial worker. Taller and fairer, hooray, you're wealthier and praised. Just give it 10 or 20 generations and see where it goes. Our large population makes it LESS likely that we will blend into one.

Fun stuff.
As for brain size, we could simply grow humans in artificial wombs. In fact that could start happening soon; no need for the pain or inconvenience of child birth.
In the short term we will be presented with all sorts of choices and opportunities as individuals and as collectives. In the long term, with the convergence of genetic engineering and technological enhancement, the only limit will be the human imagination.

because of medicine, evolution is canceled. mutations and genetic disease that would have killed a child are now passed on. we aren't going to evolve naturally anymore, our evolution will have to be through artificial means.
genetic manipulation and cybernetics will combine to create a custom creature that will fit into any environment. our entire planet could become one giant being with plug in personas. -
Can we tackle the whole, wisdom tooth issue first? There's still tons of stuff in our bodies that we don't use anymore. I think that's where we're going first, getting rid of the extras.

What, no mutant powers? That sucks!

Assuming the human species can survive mother natures efforts to destroy us and the efforts of the human to self destruct through war and violent crimes, I see humans branching off in two directions. The common citizen who has little ambition to seek technical and scientific challenges in research and invention will or rather may suffer from smaller heads due to mutation and the lack of seeking knowledge. The old phrase,"use it or lose it" seems appropriate to the issue here. I think that it is said that the average human uses about 10% of his brain capacity then all of those extra cells will just flounder and waste away, while those involved in the higher sciences will continue to use larger portions of their brain and would probably remain static for many thousands of years. I also see the possibility of babies being created first in a petrie dish and transferred to a special incubator for growth and birth. The sciences are becoming more technical and consumer friendly.

In the year 3000 thouseeeennnnnddd!
Evolution plays a trump card on the American population, given that the world did not end in 2012, Christians now have the new end of the world number as 3333 and finally elect in Power Sarah Palin's daughter who promised in her campaign not to nationalize hyper Walmarts and debunk scientist who claim, the American brain has shrunk thanks to ultra fast food pills and useless information overload.

There are going to be HUGE breakthroughs in cybernetics, genetics and nanotechnology in the coming years. Id like to think genetically engineered/cybernetically enhanced humans are going to be the future.

Cult of Man.
.........behold the "new" man. -
The next evolution we need is a change in consciousness. Advances in technology are great no doubt and will have strong influence on our health and longevity but it won't be able to solve the sorrow and horrors of mankind.
The beauty of such a change is that it can happen right now. The revolution we need comes from within each one of us. People are intelligent and compassionate, but society fosters many different kinds of skewed perspectives that last a lifetime. Some just have more opportunity to realize this than others.
Awareness of the present results in a peaceful past and future.

98% of human genes are inactive so human evolution is still in its infancy
-
You probably are not going to believe this or don't want to, but, humans will become more machine like in the future. It'll be more about super computers and machines rather than biological evolution.
Don't say I didn't warn you.
