Will everyone in the world eventually evolve and look the same?

Question

Ok, so there are changes happening to the weather everywhere and humans are constantly evolving to adapt to their environments.

Is it actually possible that humans could evolve to look the same in the world if the environment was in equilibrium everywhere?

Serious answers only please and from Anthropologists if possible.

Answer 1

NO...

Genetic variation is not that limited, and DNA replication is prone to err!

Answer 2

I doubt people will look the same (at least not any time soon).  We've been around for what 10 thousand years or so and yet we still have a far way to go to start resembling one another  I think the bigger concern though should be not that we look the same but that we're actually getting dumber.  If you look at today statistics those with college/advanced degrees are having fewer kids than highschool dropouts etc.

Answer 3

to look the same,, this word needs a lil adjustment

if the environment was in equilibrium , they will have the same qualities , like the same ability to resist heat,   considering that they are of one offspring  

i mean ,  black people developed resistance against the sun with their dark skin,  and they are passing it to their children in their genes ,  

and another factor that they won't look the same is that environment might be in equilibrium but their minds aren't .

interests vary from one to another which gives you special qualities that other people might not have ^_^

Answer 4

We might eventually lose the distinctive races because of interbreeding.  That would probably increase the variability within the "super race".  We might all be more similar if some sort of selection acted on the population but minus that the same amount of variation would probably exist in the whole population.

By super race, I didn't mean that as it was used by n***s but rather as a name for all the races combined into one.

Answer 5

I only have an interest in anthro but I think this is where that "random changes" come into play.  Maybe, for some reason, big ears become needed and these people are the ones most likely to survive then small/medium ears will still appear just less and less often. Then the situation changes so that little ears are needed then people with smaller big ears will survive until the ears get smaller and smaller. I mean, if need be, we could go back to being covered in hair.

The option is there because there are some people with a lot of hair on their body. The option is there because there is a variety of people and there will always be a variety. Even if all people died out except a few, variety would return with an increasing population. Diverse investment.

Answer 6

I would have to say No. did dinosaurs look all the same when they became extinct  no. and sadly enough i don't think we will live as long as dinosaurs did. were s******g up this world way to much.

Answer 7

No. Not environmental at all. Its all genetics. We will all only begin to resemble each other if we interbreed  as the physical barriers disappear. Its already starting. Inter racial breeding is something that just did not occur in the not too distant past, and in most countries is still not common. Who knows about four thousand more years?

Answer 8

I don't think so

Answer 9

evolution arises from differences, not similarities.  everyone would eventually become the same if there was no evolution.  you're a bit confused on how evolution works here, i think..

Answer 10

We look different in different parts of the world for a reason. You'll find darker skin closer to the equator to adapt to the intense sun. Even though we have advanced transportation, migration, and an easier way to breed with other ethnicities due to diversity especially in America, we still will continue to evolve as a whole with diversity

Answer 11

i sure hope not

Answer 12

Uh, the Earth will never be of one climate,as the sun will always hit different parts of the Earth with different intensities.

No, we aren't constantly evolving to adapt ot our environments.

No, it's highly unlikely human would evolve to look the same all over -- though we are inter-breeding with groups from all over more and more with time.

You're not really understanding how evolution works. Nor much about variation in climate.

Answer 13

We're actually evolving and becoming different. It's a hypothesis that presumes there was only 1 surviving group of a catastrophic event from which all current humans today have differently evolved from. It's called Einsteen's thesis on revolution or something like that.

Wait a minute, ..... I understand your question now. If all things were held constant would we all evolve in the same direction and eventually look alike? Perhaps, hmmm ....perhaps. But I think it was proven otherwise in the Gallapagos by Gilligan.

This is one of your final exam questions isn't it?

Answer 14

Anthropologist here, and a serious answer!

Short answer: No. Lots of animals are specially adapted to live in one particular environment, and they don't all look identical. A good breeding population has enough genetic diversity that its members are probably going to all look different. Anyway, humans are all pretty similar enough to survive in each other's climates anyway. We already do, in fact. It's not like white people can't live in Africa because they aren't adapted to living there.

Furthermore, if you don't think there's any conclusive evidence about global climate change, and humankind's involvement in it, then I'm not sure what you're reading.

Answer 15

It's possible that eventually, the blending of the races will blur the lines. Should something catastrophic occur, either a natural disaster (big m**o meteor), a plague that kills 25-50% of the population, or a war of unimmaginable size, which would significantly reduce the population size, might isolate pockets of mankind. Within these small pockets, peopel might interbreed to the point that they would more or less ressemble each other (American Indians). But seperated by the continents and oceans, devlope along different lines and would still look different. As an example, even within a relatively isolated continent such as Africa, the diversity of the African tribes was pretty amazing. Different tribes displayed a wide variety of very distinct features.

In a nutshell, I don't believe we will all look the same some day.

Answer 16

The answer to human evolution is that the rapid migration made possible by today's transportation, will bring more opportunities for procreation outside of one's traditional ethnic region.  

The reason that genetic differences arose on different islands in the Galapagos, is that once a population (of finches, to use the most famous exemple) became established on one island, the specimens who were best adapted to conditions on that island stood a better chance of surviving and procreating.

In human evolution, differences arose because of the separation of one group from another.  On the whole, humans survived and procreated whether or not they had helpful genes.  Division of labour and development of tools and medicine allowed for the weaker members to live as well as the strong.

The separation or isolation of an ethnic population is impossible today.  The pendulum will swing back toward sameness or homogeneity, due to the victory of dominant over recessive genes.  Over many generations, recessive traits such as red hair might be virtually eliminated.

Answer 17

no
