Amerindians are different ethnical native groups, not races. Don't confuse ethnicity with race. My family is from Sassary in the Cerdegna Island in Italy, so we are ethnically Italian, but remember that many Phoenicians lived in that Island, so noone can be sure about race, except by an DNA exam.
This whole race stuff is starting to get a bit boring. Anyways, I know a thing or two on Anthropology since I've taken many courses at college about cultural and biological anthropology which included some of these terms. I have mixed feelings on Evolution and lean more to believing in the righteous Biblical people and G-d and how this all turned out. Some of the classes were way too liberal for me and glad I finished taking them.
I don't know why this whole race stuff comes up on the forum. I just can't see Apes evolving as Humans, but that can be discussed in another thread. Well, I guess some people are interested in taxonomy on the forum about the world's people it seems. Some of the Anthropological concepts and Population Genetic concepts are far-fetched, complex and some hard to believe.
You can belong to a larger taxonomy of people like Mongoloid but there are differences inside the wider spectrums such as Mongoloid. For example, American Indians, South American Indians, and Siberians are in the Mongoloid spectrum but they aren't necessarily the same as East Asians, such as Chinese or Japanese, yet they are grouped under "Mongoloid" with East Asians.
Some Contact races have come together in the last 500 years and are considered their own people. Although in some cases Contact Races have a predominant tendency toward a Taxonomic group such as Caucasoid, Mongoloid, Negroid, Australoid or Capoid.
Some indigenous peoples show and have affinities with people of larger taxonomic groups such as f.e. Mongoloid, others are their own group like Australoid.
White isn't a clear term. People have their own definition of White. The terms which group similar peoples into Mongoloid, Caucasoid, Contact Races (f.e. Mongoloid-Caucasoid) etc. is pretty clear.
Taxonomy in the wider sense:
Caucasoid = Peoples of Europe, North Africa, Western Asia and parts of India. (Semeticoid (Middle East/Sephardic/Persian/Afghani/Bukharian-Uzebek/Tajik/Azer/Turk/Tajik/North Africa non really black people etc etc)) Hindisoid (Like Indians/Paki/Sri Lankan etc) and Gypsies. Some Indians have Australoid influence especially in central and southern India. Australoid variants that survived in parts of Asia so they are apparently a group of their own. Some Gypsies also have old Australoid traits since they originated in India, but they are mainly Caucasoid.
Australoid = Australoid with perhaps indigenous variation or variants.
Mongoloid = East Asia, Pacific Islanders, Indians, Cherokee/Aztec/Mayan etc/Native North Americanoid (American Indians are in the Mongoloid spectrum, some have more Caucasoid tendencies due to the European influence on American Indians, there are also Black Indians from African-Americans).
Negroid = Africanoid (Yo Yo whazzup, pretty much black, does not include Morrocans, Lybians, or anywhere in North Africa)
Contact Races = Mulattos, Brazilians, Mutts, Hawaiians, Philipinos, Negritos etc. and other peoples are contact races meaning they have tendencies and influence from Mongoloid, Caucasoid, Negroid, or Australoid peoples. Polynesians are more Mongoloid for the most apart. In a way Polynesians are in between Mongoloid, Australoid and Caucasoid, but mainly Caucasoid and Mongoloid.
Javaoid/Indonesianoid are mainly Mongoloid, with others having tendencies and influence from Caucasoid or Mongoloids in a way they are also like contact races.
Most Contact Races have their own specific phenotype due to the mixture and the way everything turned out. In a way, I guess you could say it is now an indigenous Biological mixture, but thats a bit skeptical. Some people in Contact Races show more traits and tendencies towards Caucasoids, Mongoloids etc.
Other = At most probably Contact Races or individuals that aren't sure what they are.
There is also controversy whether there is a Capoid race. It appears to be becoming extinct and absorbed in the Sub-Saharan Negroid people. Most of these terms are outdated and no longer in use, though in some circumstances like forensic anthropology etc. they are still used for taxonomy or murder cases. Most of these were coined by the Anthropologists such as the racist Carlton S. Coon and a few other racist European Physical Anthropologists along with the Nazis in Germany, who in general had their own crazy racial agenda and myths, who were against race mixing. The Nazis invented some of the worst Anti-Semetic Dreck propaganda and used Anthropometry, skull craniofacial measuring etc. to determine whether one was "Untermensch" or "Aryan." A smaller head doesn't mean your less intelligent. All of these turned out to be fallacies and historical lies as modern genetics proved this wrong.
Congoid = Negroid or Africanoid
"The term Capoid implies a judgment that they are sufficiently distinct from Congoids to warrant dividing the Negroid race into sub-races. This was originally made on the basis of visible physical features, but more recently genetic studies have shown the Khoisan to be distinct from all other peoples in some genetic markers; there is also a high level of diversity between different Khoisan groups, indicating they separated long ago.
Recently, it has been suggested that the first anatomically modern humans to migrate out of Africa and give rise to modern humans in the rest of the world were similar to the Khoisan. While some genetic markers shared between Khoisan, Ethiopians and non-Africans can be interpreted as supporting this hypothesis, it is anachronistic to identify a modern race with one alive tens of thousands of years ago."
