If there were for whatever reason different population types stopped interbreeding ( not races) . For example if the ugly only breeds with the ugly and the beautiful only breeds with the beautiful.

it's possible given enough time for humans to seperate into two or more species, but most likely it would be because of spatial seperation. For example, if humans went and colonized a far away planet and lost contact with earth for a million years, then it's possible that the two species would vary enough that they would genetically unable to have children, thus by definiton be another species. This would become even more probable if the colonized planet had a different enough enviroment that it forced the native humans to evolve in a different direction, and if the orginal population was small enough so that it would undergo genetic drift.
That however is an unlikely scenerio. If however enough time actually did pass for human speciation to occur, we will probably have mastered genetic manipulation to point that we could just change our DNA structure any to express any phenotype we wanted anyway, making the issue of speciation almost a moot point.
At anyrate people regardless of mate choice keep the same standards of beauty imprinted in their brain. Just because someone is forced to choose an ugly mate doesn't mean that they're children won't desire what we normally consider beauty in their partners any less then attractive families. Nor are class divisions stringent enough in human societies to cause speciation, even over long periods of time.
So the only instance where I can see future speciation in humans is physical seperation for vast periods of time, or if humans were purposefully manipulated genetically to the point were they couldn't interbreed normally.

a number of the failings he says are spot on- like that people ought to have espresso colored epidermis- completely maximum perfect- and this guy is a respected scientist with the help of many people, so i wager alot of people imagine what's says is real. Me for my section- i low-priced as common sense something printed contained in the each day mail newspaper because they tend to be oppressive in words of sophistication, gender, subculture, faith and so on. very last week a vacationing scientist became banned from doing a communication the following with the help of a museum- the scientist had a nobel prize for his analyze into stem cellular/DNA analyze, he had suggested that he had concluded that black people were a lot less wise than white. Which common sense defines thats utter garbage-so theres continually some loopy scientist round, too a lot blending with chemical substances in labs can impression the mind thats what i say.

. IF two populations stopped interbreeding, they WOULD evolve into two different species. If there were occasional interbreeding, it would be sufficient to maintain their close relatedness.
. In nature, this only happens when a natural barrier arises, dividing a population into two populations.

Im afraid not, besides the fact that there is no "ugly" meter, or no beautiful meter to determine those things. It would be impossible even if we tried. But to answer the question, it lies in genetics.
If you mate two people with a big nose, it doesnt mean that your going to get a child with a long nose. Its all random chance and genetics. There will never been another human race nor will the humans ever evolve into anything. NO evidence supports that theory and no evidence ever will.

Contrary to what "elite" said, there are many different races of hominids. It may be true that only one of them should be called human, but I'm sure that's not what he meant.

It already has, at least here in the US. Witness the backward-evolving "Homo Gopfundy Unsapiens" sub-group, where intelligence appears to be a liability.

No. Like the first person said, people look the way they do based on growth after birth, not a particular genetic code.
