What are the different types of human beings on Earth Is there only one type of human being on Earth

Men, women, bad guys, good guys, wicked guys, good guys.

Yellow, white, black, three.

Three types: men, women and ——— female doctoral students.

I heard that.

There are two kinds of human beings on Earth, men and women.

There are two kinds: those you have a problem and those that don't.

Men and women.

Good guys and bad guys.

Chinese and foreigners.

And so on and so forth.

Yes, there is only one human being on Earth.

In terms of biological classification, humans belong to the kingdom Animalia, phylum Chordates, subphylum Vertebrates, Mammalia, Primates, Anthropology, Homo sapiens, Homo sapiens, and Homo sapiens. There is only one species of Homo sapiens, and there are no subspecies, subspecies, etc.

Although there are differences in average height, skin color, hair color, iris color, etc., among humans living around the world, they all belong to different body characteristics and do not represent differences in the structure and number of chromosomes. So it's all the same Homo sapiens species.

Humans all over the world, regardless of skin color or level of civilization, have no reproductive segregation, which means that they are of the same species of Homo sapiens.

There is one kind in existence: that is, Homo sapiens. There are about 14 species of humans and one species of unknown species.

Four kinds: men, women, good guys, bad guys.

According to the skin color, it is divided into three types: black, blue and white.

There are three types. Men, women, and another kind: people like Li Yuchun.

According to the difference in skin color, the mouth of the world's human steak hall can be divided into three major races, namely yellow people, white people, and black people

So the answer is: Caucasian; yellow race; Black people spring skin hidden.

One class of thrift seems to live forever, and the other class of luxury seems to live tomorrow.

The people of the world are usually divided into four races: Mongoloids or yellow people, with yellow complexion, straight hair, flat faces, flat noses, and wide nostrils; Caucasoids or Caucasians. White, high, narrow nose, wide range of eye colors and hair types; Negroid, or black, is black, with thick lips, a wide nose, and curly hair; Australians (australoids) or brown people,** brown or chocolate color, brownish-black and curly hair, broad nose, well-developed beard and body hair.

There is no consensus on the classification of modern human races.

At present, there is only one species of modern human beings in the world, and the black, white, yellow, and brown human race is a racial problem, not a biological species, and all existing human beings are one species, and the differences between them are not even enough to the extent of subspecies. Biologically, the current human beings belong to the phylum Vertebrates, Mammalia, Primates, Hominidae, Homogenus, and modern humans.

Recently, scientists have found from the history of biological evolution and genetic comparison that chimpanzees should be different species of the same family (Hominidae) as humans, rather than the same family as gorillas and orangutans, but this assertion is being adopted.

2 humans, 1 human, 1 non-human.

The world's races are mainly divided into: white, yellow, and black.

The white race, also known as the Europa race, is the most populous race in the world, accounting for about 54 of the world's total population. Caucasians tend to live in colder regions. Caucasians** have low melanin content, ranging from white-red to dark brown; The hairs are numerous and soft, appearing as wavy blonde or brown hair; Dense body hair protects against cold; The eyes are blue, the nose is high and narrow, and the nostrils have long passages, allowing cold air to enter the lungs more slowly.

The yellow race, also known as the Mongolian race, is the second largest race in the world, accounting for about 37 of the world's total population, half of whom are Chinese. The ** of the yellow race is pale yellow to brown; There is little body hair, and the hair is straight and black; brown eyes, broad flat face, broad forehead;
