People,serching through human history we will see that in the pre-history,people would have to put their lives at risk in order to kill animals to eat.They spent much energy to do everything and obesity was almost non-existing.Latter,humans created agriculture.That was the first step to sedentarism.We created animals and planted and this had led to the first cities and the society we knoe today.

Thousands of years later,industrialization begun to dominate the world.Nowadays it makes much more delicious food han in the past,the modern technologies made our lifestyle much more sedentary and life will be even much easier,comfortable and sedentary.Nanotechnology eliinate the need for humans construct anything with their hands,every home will have robots to do everything,artificial intelligence connected to our brains will allow us to learn in microseconds what we take years to learn,and even further in he future we will have matter replication that will give us anything we want.

Will such technology lead us be so sedentary like in the movie Wall-e?

Life will be so easy that people will forget that lesson of life that says that life is difficult for everyone...Do you think that?We won't have difficult to do anything...

I don't think we'll be obese unless we want to be.

I don't think we'll be obese unless we want to be.

Not just being obese,but being so sedentary that our body will change,our bones and muscles will be so very weak due to the lack of exercices that we will need to move on antigravity machines ...and giving us a flabby appearance...

Do you think that this will be possible if we continue to get more and more sedentary like in the movie wall-e?

[shane_allen]

Jesus, with the wall-e thing again...

What you're thinking of already exists. Being fat is huge in america, right now. So, I guess yeah, you're right. But I should clarify that I'm talking about in a couple decades, I don't think it'll be an issue in the least, even though we may be more sedentary then ever. It's a quick fix to keep your bones strong and your muscles lean and the fat off when genetics are as easy to change as they seem like they will be.

For an example, in this talk Dr. William Li shows a mouse that was engineered to be obese. That's not the interesting point, it's the anti-angiogenisis used to make it thin. While the "cure" in this case wasn't genetic, it was an effective treatment that didn't require exercise. The part I'm talking about begins at 16:34.

(I'm just jabbing you with the wall-e thing, by the way. No harm intended.)

I think there will always be people who feel the need to stay in shape and those who are fine with sitting around. In the future, I can see the latter people getting more sedentary. Not sure what that would do to the overall numbers of healthy vs. unhealthy though. And what happens when you throw ultra-realistic VR into the mix? Hmmm...

[CyberMisterBeauty]

The objective of the topic is not only talk about sedentarism and increasingly food comsunption,but also talk about the evolution of technology and this making us less and less physical active.For exemple,130 years ago,didn't existed automobiles or phones,so everyone should go by feet to visit other peolple and didn't existed eletricity,so didn't existed elevators,roller stairs etc...

Nowadays most people have cars,phones and comodity are everywhere and food portions are getting bigger and bigger,so the result of all this is the obesity epidemy that many countries suffer nowadays...

And yes,Shane_allen,we can solve obesity using genetics,I just asked your opinion if technology could lead us to the scenes of wall-E,when tech is so advanced that even the need to walk was eliminated...

[EVanimations]

I think that what would happen, is that due to modern and futuristic conveniences, the only place natural evolution could take us is neoteny. After a few generations, fully grown adults will appear suspiciously like modern teenagers. Many generations after that, fully grown adults would resemble oversized toddlers. If you want to get really extreme, fully grown human adults would resemble fetuses. Neoteny has happened before...all vertebrates owe their existence to the tadpole-like larvea of the Sea Squirts.

As to the topic of obesity, I fully expect for there to be a cure (be it drugs or some metabolism-boosting surgery) that would eliminate the obesity epidemic, and only those who want to stay obese, for whatever reason, would indeed stay that way.

I do believe that technology would have a toll on our physical forms, but not so much in a Big Fat Future way.

[Alric]

I think as technology improves and we become far healthier we will be more active. If you can watch tv and surf the web from any where you want why stay home? The only real reason is because its more comfortable, but if you are in perfect health, or even have super human health and all your luxuries are portable and can come with you, then it isn't going to be any more comfortable.

I don't think future adults will look like teenagers,unless you are talking about women or ectomorph people,I think a 35 years old man will never have a body of a 14-15 years old boy,unless he has some kind of muscle-wasting desease...I think future adults will have an younger appaerance in the sense of having less body hair,less facial hair,more soft features and a more youthful overall look.

That kind of transformation you said will require extreme genetic modification in a few generations...

[SG-1]

Do you even know what neoteny is? No one can know for sure what humans will evolve into, if they do at all.

I'm pretty sure that I have a good idea. Which one of us are you talking to?

For those who don't understand it, neoteny leads to pedomorphism, which is a form of speciation when traits from juvenility are retained into the adult phase. Basically, we'll evolve to look younger over generations. It's a driving force in evolution.

Humans apparently already have neotenous traits, according to wikipedia- flattened faces, small teeth, large craniums, and relative hairlessness.

Who's to say further conveniences in technology won't make us look more like babies? Softer foods may make our teeth smaller, our jawlines less pronounced, and sedentarism may make our limbs weaker.

The process will happen over hundreds of generations, which takes way too long for anyone to notice. Adults that look like our 13-year-olds may just be the norm come 5000 A.D. or so.

[CyberMisterBeauty]

Well,now I understand,only after hundreds of generations maybe 30 years old men will look like 12 years old boys...what you said really make sense to me now...another thing:Do you think because of technology men will evolve into a more feminine appearance,like less body/facial hair,ausense of addam apple,less muscle mass(a thinner body),ausense of baldness and a softer skin and a more youthful face?


In other words,look like bishounens of animes...

Edited by CyberMisterBeauty, 12 April 2012 - 11:22 PM.

[EVanimations]

hm...maybe. However, if anything, the baldness trait will most likely become more prominent in the gene pool. I can see us reaching the peak of our physical prowess by about 3000 A.D., resembling hot, nubile 20-somethings. However, there will be a slow decline following this trend, as people will begin to become more and more like modern infants. I think our immune systems will definitely become weaker, unless we have some immunity-boosting gene engineered into us by then.

Back to the main topic though, yes, in the shorter-term future, more people will continue to get fat.

At least until some perfect weight-loss drug or metabolism-boosting genetic trait is engineered, people will refuse to get off their fat asses to do any kind of hard physical work.

[CyberMisterBeauty]

Do you really think evolution will make men will have a more feminine face since women prefer men with feminine appearance?Do you think that some traits that were common to man in the past will emerge again like long hair?


Just curious,are you male or female?

[Alric]

A lot of people think that humans have stopped evolving at the biological level, and I generally agree with that. There is no pressure for us to evolve any longer, and everyone has a fairly equal chance to pass on their genes no matter what. Even severely crippled people are fully capable of having children that survive. Without anyone having any real advantages it seems unlikely that we will move in any direction. Instead everyone will remain roughly as they are and any changes will just be spread out among the gene pool and likely not have any lasting impact.

[CyberMisterBeauty]

None of you anwered the question of the topic:Do you think that with technology will make life so easy,and food will be accesible everywhere(matter replicators),we will eat much more and do less and less exercises,and this will make us be very fat and sedentary,making our bones and muscles have a density of a baby's due to the lack of exercices,just like in the movie Wall-E?Machines are everywhere,replacing people in everything,and the latter only eats and don't do any physical exercise,due to such technology...


By the way,what do you think will happen in the next decades:People will begin to worry about their health or will we eat everything in front of us?(Like in the movie Wall-E again! )

And about neoteny,why do you think in the future adults will resemble toddlers or fetuses(disgusting!)And this thing only applies to appearance or adults will have a more childish and immature behaviors and personalities as well?

I do not believe in evolution from Apes as I expressed many times in the past forum. However, body and appearence and even genes modify according to the enviroment we live.
I don't think we will see much change in the next following years. Maybe we will more arthritis prone because of luck of movment, however this is a risk that will take place only in the next 50 years or so. Stem cells will repair our bones, genetic therapies will make us more fit and even fat pills will prevent us to become obese.
When technology will be more advanced I think that humans will move even more, sport, leisure and an increase of social life will make us more active and less sedentary.
You will hardly see fat pepole in the future except for the rare cases of pepole like that typology of the body.
How the behaviour of humans will change? Thats a big question mark. We may either be less stress and therefore more prone to give love to eachother and less selfish or we may become very selfish regarding ourself as God. There is also a risk that some sentiments will fade away because everything is so easy and not longer appreciated.

Whaa...?

So 96% DNA similiarity between human and chimp is what? Coincidence? Whole tree of evolution i false?
And genes modify according to the enviroment? What does that mean? My DNA samples from 20 years ago would be diffrent from present ones?

I am not going to enter in this long disussion again. In the last forum it went on for about a month. So I will close here. The only thing I can tell you, look on critics to evolutions. There is a valid scientific literature on the subject which is substained by scientists.
Also we always talk about theory of evolution not principle.Here I close.

  Yes- Recent reserch claims that genes have small changes in our life.
  
  and it takes some generations before genes of ethnic groups change
