why do mongoloids have similar physical appearance?
91106
actually they don't look similar, it's just that you/we can't distinguish them from one to the other. The same thing happens when a mongolian (who is not familiar with caucassians) sees a bunch of white people... they look all the same!!

Traditionally they've been classified as:\nCaucasoid - in Europe, the Middle East, and India (all have wavy hair, thick body hair, and prominent noses)\nMongoloid - Central, Eastern, and Southeast Asia, and the Native Americans (straight black hair, broad faces)\nNegroid - in Africa (curly black hair, dark skin)\nAustraloid - the Australian Aborigines (dark skin, wavy hair)\n\nthe "mongoloids" are cold adapted, they came from Siberia\nthe "negroids" are heat adapted\nthe "caucasoid" and "australoids" are more "primitive" so they never really developed adaptive features\nHowever, these adaptations are meaningless now, since we have technology and brainpower to survive\nAlso, these descriptions are somewhat useless since all human races can interbreed with one another, meaning we're all really one race\n\nMany of the terms have been discarded since some of them sound offensive (mongoloid, negroid)

My only guess is that biologically they are much more visual than women are and need tangible evidence of there existance. Feats accomplished and places gone and things mastered provides that sort of evidence.\n\nOr the short answer: Testosterone.

>>>> Why do chinese people have chinky eyes?\n\nAcceptable common terms are slanted, slit or (preferably) Mongoloid. Chinky is just plain offensive.\n\nAnyway Chinese people have slit eyes because the skin beneath the eyelid fold  folds upwards over the eye to some degree, producing a partial third eyelid know as an epicanthic fold.\n\nWhy do Chinese people have an epicanthic fold? Because humans evolved with an epicanthic fold. That particular feature isn't restricted to the Chinese, it is found amongst all East Asians and Native Americans and perhaps most surprisingly is also normal in the Khoi-San peoples of Africa. It is assumed that the first humans had the same basic eye shape found today in Chinese and San. Other human populations have since mutated in such a way that the epicanthic fold has been lost while Asians and San retain the ancestral condition.\n\n>>>>Why are there white people and black people?\n\nThere aren't. There are only two major skin types in this world: brown and not-brown.\n\nThe ancestral skin colour is assumed to be the brown colouration seen mostly amongst the Khoi-San and some South-East Asian populations but also fairly common amongst North-Western Europeans.\n\nThe brown skin type maintains the colour producing units of the skin in discrete clusters. The non-brown skin types have those colour producing units spread throughout the skin evenly.\n\nBlack and white skin are both largely the same, and both are of the non-brown type. the only difference is how much melanin the skin produces. There is no point at which you can say that a skin type stops being brown and becomes white as there is with the difference between brown and non-brown skin colours.\n\n\nThe reason some people have darker skin is because the skin has produced more melanin. People at the equator tend to have darker skin than people living further north or south, but it's a very poor relationship.\n\n\nThose people telling you that black skin relates to life in warm climates obviously aren't thinking. Brazilian Indians live in warm climates but they don't have black skin, and Tasmanian Aborigines live in cold climates and they do have black skin.  Skin colour has very little to do with climate and a lot to do with ancestry.

John is actually incorrect... our characteristics are not governed solely on out genes, there are many factors that are involved.\n\nSome characteristics such as hair colour and eye colour are govered by our genes, but we can actually appear differently depending on how we developed in the foetal stage of development, as well as injuries we may sustain, what we eat, how we live, and psycological responses that lead to hormonal responses (or vice versa). All of these can change markedly our characteristics.\n\nSome simple examples include 'wide feet', spinal malformation (eg. muscular scoliosis), asthma, and many more. Note that these may be influenced by genetics, but having the gene does not mean you get the characteristic.\n\nConsider that two identical twins can actually be told apart becasue one is often slightly taller, or slightly fatter or has different characteristics, however their genes are the same.\n\nConsidering that the environment in the womb during pregnancy can change a human's characteristics quite markedly as it can also change hormonal development, then we must realise that if you were to be cloned then your clone may look very different from you... although you will most likely look similar enough to look like siblings.

their snout and the lengths of their physical bodies.

Because of evolution.  Ugly people are frequently people who have errors in their genetic code.  They usually lack symmetry.  In the desperate world of the caveman, those people who were born with congenital defects (were ugly) might not live long.  They posed a risk to the survival of the group.\n\nWe have evolved from a long line of survivors... we have been bred to hate ugliness as an instinctual response.  This doesn't mean that this instinct is still a beneficial thing.  Our culture has evolved  to where physical appearance doesn't need to be as important.

Because they have epicanthic folds,which make the eyelid shape,as an ethnic characteristic.

lebanese are classified between caucasian and mongoloid so there is a possibility of blond hair and blue eyes. probably not in a pure lebanese person though.

A lot of it is nutrition.  Their diet is highly based on rice and grains, and thet does not allow for a people to reach tehir full genetic potential.  \n\nLook at the historic rates for height and you will see that in all countried there has been a trend towards taller.  Look in your history books for the average height of a  male in the US.  You'd be surprised.\n\nWait a few generations and the Asians who have adapted their diets will be just as tall as the other races.

maybe coz u think they look the same

Very slight differences, but not enough to classify one race as superior or inferior at any event.  For instance, Norwegians tend to be taller than Southern Mexicans, but that has no bearing on anything.  It's pretty much a myth.  It more has to do with genetics from the direct ancestors.  Good question!

Its the same genetic make-up as any two brothers or two sisters. Since they develop from two different eggs fertilized by a sperm each

they must be look like regular people because they are just humans and all humans are the same

That they are in the same kingdom, phylum and class? So they share similar traits the way we share traits with other primates.

It is the sole reason for such diversity in the human species. It is the reason why siblings, even identical twins, eventually diverge into their own personalities. Since no two individuals have the exact same neurological framework, no two individuals in this world are the same. Even clones would not grow up to be exactly alike since the external environment plays a role in building neuron connections.

Supposedly Tutsis are taller and have sharper noses, but in reality, they are usually indistinguishable. They may have been much taller in the past, but that is likely because they had much better nutrition than the Hutus.
