The human race will eventually die off?

So today at school my teacher said that in the future, humans will have mixed so much that everyone will look the same. Then, because their isn't much genetic variety, it will be like having babies with a cousin or sister. Then the babies will be deformed and wont be able to reproduce and eventually the population will decrease since hardly any humans are being made and then we will become extinct.

Is this true?

If so, that would suck to be in the last generation of humans.

It's true. Hooking up with someone of my own race is just like scoring with my cousin.

you sure that was a teacher and not a mentalist in the street with a dog on a piece of string?

Is this your teacher?

That theory doesnt make sense. If all the different races started interbreeding, I would suspect there would be more genetic diversity not less.

"humans will have mixed so much that everyone will look the same"

That's where he failed at. An odd ball always comes out with something unique. Almost like a rare shiny pokemon.

It sounds like far fetched but im sure your teacher knows better than I do.

But it will probably take an extremely long time before that would happen and im sure that the human race would die before it because of other causes, maybe the next ice age or something else.

I find it hard to believe that mass inbreeding will be the end of humanity, odds are it will be destroyed in some other way before that even happens, if it ever does(could).SaintLeonidas

What class is this teacher teaching? If it is in a biology class, I can only react one way. xaos

[QUOTE="kussese"][QUOTE="thegerg"] Nothing in his post should lead anyone to believe that his teacher believes skin color=same DNA.

thegerg

A population larger than a thousand will maintain and develop good genetic variation. So no, it won't end that way.

EDIT: Also, race doesn't strictly exist, what you refer to as "race" gradually changes in populations with geographical distance (excluding isolation and migration/genocidal conquering).

[QUOTE="kussese"][QUOTE="thegerg"] Nothing you just posted has anything to do with the fact that nothing that OP posted should lead you to believe that his teacher thinks same skin color=same DNA.

[QUOTE="thegerg"]
Your first post was anout skin color and DNA, now you're not even mentioning skin color. Your next post mentioned DNA and race, eventhough there is no genetic basis for race distinction. Now you're making silly accusations of trolling. You seem to be upset and/or confused.

thegerg

Really?Second entry down: ethnic group. "Color"

[QUOTE="thegerg"]

[QUOTE="kussese"] Either elaborate on how he could *possibly* be implying anything but that or quit trolling. It's transitive. Everyone will look the same = same race. A = B. Everyone will look the same = little genetic diversity. B = C. Little genetic diversity = little difference in DNA. C=D. Therefore A = D. This is not complicated. The teacher is a moron. Are you saying you disagree? kussese

Oh lawd.

Some "Hispanics" are now "Caucasians", some "Caucasians" now "East Asian", some "Africans" are now "Hispanics" and alot of Mediterranean dwelling "Caucasians" are now "Hispanic".

Thats even more laughable than the accepted perception of race.

Not gonna happen that way. Gene therapy's going to kill any undesirable DNA that crops up inside a human body by that point.

[QUOTE="kussese"]

[QUOTE="thegerg"] This is where you seem to be getting confused. Race is not a synonym for skin color.

Bottom line, the teacher was saying that humans will eventually breed in a manner which leads to little genetic diversity and will result in a human race in which all people look similar. That doesn't mean that the teacher was saying same skin color=same DNA.

Okay. I took it a step far. I assumed (well, still assume, actually) that she heard this theory and made a massive leap of faith that because when it happens to skin color, it happens to everything. Most bodily features (skin color being the major exception) don't converge to an "average."

eventually we will do so much that we do nothing at all

derp

Lol that dosen't make sense. There will always be some kinda of unique gene.

"undesirable" DNA could be eliminated without thought for its uses. What and who determines what genes are beneficial to the species? Alternative traits could be discarded in favour of the socially desirable trait, leading to specialised populations with little variation in that trait.

Even screening to remove disease causing or disease risk increasing genes, although it seems like a good idea, may have consequences for the population latter on.

Basically, in my opinion, gene selection/screening should only be applied to deadly/crippling diseases - for anything else, it should be left alone.

I presume that if the TC's premise is true and we get deformations in our babies due to interbreeding, then that would classify as a form of "undesirable DNA".

No this can't be true because if it was then we would all be dead by now based off the logic your teacher used.

I've never heard of a recessive gene that is needed for humans to survive. Whatever genes we have now is fine since we are obviously currently living.

I believe humans will move into space and eventually evolve into a different classification.

your teacher is right

Your teacher knows absolutely nothing about genetics, I'll say that much.

That theory doesnt make sense. If all the different races started interbreeding, I would suspect there would be more genetic diversity not less.

sonicare

There would be more genetic diversity. It's when there is less genetic diversity that things start changing. People should look up what happens to species that get separated on islands.

That is probably one of the dumbest things I have ever heard. I do doubt though that humans will survive more than another hundred years the way things are going, between war, and the earth getting all of its resources sucked dry.

Your teacher got his/her degree in a box of Cheerios.

It sounds like far fetched but im sure your teacher knows better than I do.

That doesn't make any sense. Race mixing (for lack of a better term, Some one please correct me if there is a better way to say it) doesn't lead to inbreeding. It does nothing to reduce genetic diversity. It only increases it.

But yes, humans will die off eventually.
