Human evolution? How do you think humans will evolve? Physically - loose our finger nails or hair?

Question

I like alot of the answers the same. What shall I do. I must be having a blonde moment.

Merge several of your answers together and at my artistic view omg were ugly. Keep going can't deside?

Answer 1

I think if we survive for millions or tens of millions of years we'll most likely become living fossils, like the Coelacanth. Because humans use our intelligence to change the environment to fit US, instead of the other way around. Our intelligence removes the impetus for us to evolve. When we move into a cold area we learn to steal something else's fur long before we could evolve our own. When we move into a desert we learn to dig wells long before we could evolve to fit the desert. We have no reason to evolve.

Come back in a hundred million years and (provided we're still around) I expect the people you meet wouldn't look very different from people today at all. They might not be interfertile with you anymore and they'd probably have somewhat different hair, eyes, skin color etc. just because of random genetic drift but they'd probably still look familiar as humans.

Alternately, we may use cybernetics and genetic engineering to change ourselves out of all recognition long before natural evolution could make any significant impact on us.

Answer 2

A species only evolves significant changes when they are advantageous, and those without them die off. Humans have nearly mastered their own environment. The only things that selectively kill humans with particular traits now are things like heart disease. However, heart disease generally kills people after they've had time to breed, so it doesn't have much of an evolutionary impact.

Additionally, it is likely that humans will be able to engineer their own DNA within the next century, rendering natural (slow) evolution obsolete.

FYI: Things do not disappear simply because they are no longer needed (such as body hair). Body hair would only disappear if the hairier humans were selectively killed before they could breed, and even then it would take thousands of years to eliminate it completely.

Answer 3

Actually the basis of evolution is natural selection and for natural selection to work some individuals must survive better and reproduce more than others because these individuals have better suited traits for their environment. Since, for the most part, anyone can have as many babies as they want (and welfare will keep them alive, they don't have to be suited to the environment at all) and unless your a very sick kid most people surivive to reproductive age evolution doesn't work on people anymore.
I'm not saying people never evolved, (we did evolove from a common ancestor we share with other apes), but ever since we began manipulating our environment to suit us (gas furnaces in the cold, house boats in the water etc) environmental pressures (the forcing factor of nautral selection) no longer effect us.
We therefore probably won't evolove anymore unless society collapses and we have to fend for ourselves again.

Answer 4

Al these answers seem ill informed on evolutionary theory. Evolution by natural selection works on the variation presented by mutation in the genome coupled with the proper selection pressure. This does not even take into account sexual selection. Evolutionary theory is a better predictor of the present from the past, rather than a predictor of the future.

Answer 5

people , animals and flowers are evolving nonetheless . on an identical time as we talk of evolution we don't count quantity years in hundreds . this is in million years or greater . yet each and every era is recuperating upon the previous . our infants are taller greater powerful geared up and greater smart . "Homo sapiens" will exchange into "Homo genius' etc. Chanakya and Buddha traveled long distances without vehicle( eco friendly) . Plato, Socrates, Pythagoras and others expressed their genius without information from laptops ie progressed nicely in strengthen .

Answer 6

Humans aren't going to live long enough to evolve significantly, but if we kept alive with our computers and cleaning robots we'd become amazingly small and frail. The antibiotics we take would slowly kill our immune system, we wouldn't loose our hair most likely because many people find hair attractive, we will loose our fingernails eventually because they do not have any real impact on our lives.

Here's how evolution works! :D
Jane and John have a baby. Baby has similar DNA to his mom and dad, but there are mutations in it. Small mutations over time lead to helpful or harmful things like limbs, flippers, gills etc... Since most people like hair, the people with hair are more likely to mate, and so more likely to pass on their hair gene. If hair wasn't attractive, however, the odds of them mating would be less, and so they may not pass on the hair gene and it would disappear eventually.

Evolution isn't "the fish grew legs to get out of the water" Evolution is "The fish needed to get out of water, one fish could be out of water a little bit longer then the other fish so it lived to mate. It's offspring could live out of water longer too. Eventually mutations led to legs over millions of years."

Answer 7

Humans who produce offspring send their traits to the next generation, thus inducing evolution. Based on what I'm seeing right now in terms of which demographics are reproducing at high rates, in a thousand years we're all gonna be pretty stupid, considering that uneducated people reproduce more often and faster than educated ones.

Answer 8

Our time of natural evolution is over. From here on we'll change ourselves voluntary by merging with our computers. In our lifetimes we'll become a new species and leave the flesh.

Answer 9

LOL. This sound crazy but I think we will
1. smaller brains- so much technology that we don't have to do much any more.
2. panda eyes- It's kinda obvious 'coz we sit infront of the computer/tv most of the time.
3. long fingers- for typing on the keyboard.
and
4. fatter- since technology can do so much, we wouldn't need to get out of the sofa.

Answer 10

Now if you were a girl would you really date a hairless guy without fingernails? Average height will increase to 6'1" though.
