Why Asia have the largest population, Europa follows Asian ( Europa sent many of it's population to America ) yet Africa be the so called mother of humans has lower population then either Asia and Europa
Asia has a very favorable environment for extensive foodsupply and limited amount of natural disasters
Asia got a head start on the founding of civilization because of its east-west orientation. When a population invents the technology of agriculture (actually the twin technologies of farming and animal husbandry), it suddenly has surplus food, and no longer has to consider neighboring populations as hated and feared competitors for a scarce, vital resource. Once communities have established friendly relations, they begin trading, and commerce enriches everyone. Obviously two of the most important things to trade are the plants and animals that are cultivated/domesticated for food. In a region with an east-west axis, plants and animals can be traded over long distances because the climate is roughly similar along the way, and these people end up with a rich agricultural economy that helps them prosper and allows a tiny but significant portion of the population to have "careers" in "industries" other than food production and distribution. Making pottery, baskets, clothes, furniture, hunting weapons -- discovering new technologies -- enriching their lives with art, literature and music. Civilization arises early in such a place. But in a place with a north-south axis, it's very difficult to trade plants and animals with distant neighbors, because they won't thrive--or might not even survive--in a much different climate. Asia had the advantage of being colossally wide. From Turkey to China, the various cultures traded plant and animal species and the entire continent benefited. Eventually that trading route became known as the Silk Road, and was still in use until very recently. North Africa was, for all intents and purposes, contiguous with Asia and simply made that swath of contiguous civilizations even wider, as the Egyptians traded with the Babylonians, Harappans (forerunners of the modern Indians and perhaps the ancestors of the people who speak Dravidian languages), and Chinese. But the climate in sub-Saharan Africa was too different, making it difficult for the tribes down there to benefit from the food technologies of the Asians and North Africans. For this reason, it was slow to develop and much of that part of the continent was still in the Neolithic Era (late stone age, i.e., agriculture with only stone and wood tools) when the Egyptians and Asians were already two paradigm shifts ahead of them: through the Bronze Age and into the Iron Age. Neolithic technology simply cannot feed as many people as Iron Age technology. Iron plows, for example, increase the productivity of farming by an order of magnitude. The wheel (a Bronze Age technology) greatly increases the efficiency of transporting food. Note that from a geologist's perspective, Europe, Asia and Africa are a single continent: Afro-Eurasia. Nonetheless like Africa, Europe lagged behind the technological developments of Asia because its climate is a bit different. It's similar to northern Asia, but northern Asia is not where the population centers were. Nonetheless, when the Indo-European tribes found their way to Europe and displaced the ancient Cro-Magnon stone age culture, they had already developed agriculture, metallurgy and the wheel, so they simply imported those technologies to their new home rather than re-inventing them, giving the continent a head start. But it's the Americas that were a nightmare for a Neolithic technologist: a north-south orientation that reaches all the way from the arctic north, across the steamy tropics and the equator, into the temperate south. Farming was invented in at least two different places (Mexico and Peru), but the crops could not be established in neighboring locales because the weather was wrong. Animal husbandry was an almost total failure due to lack of biodiversity. The largest animal domesticated by the Incas was the llama, and female llamas produce so little milk that it's a wonder their calves even survive to adulthood. The largest animal domesticated in North America was the turkey! Grains are the lifeblood of the human race once they invent agriculture (because they contain a lot of protein), but the only important grain in the Western Hemisphere is corn/maize, which is nutritionally almost worthless compared to wheat, rye, rice, etc. It's hard to feed a growing population on corn and peanuts! (Legumes also have a lot of protein, which explains why soybeans are such an important crop.) The first civilizations weren't built in North America until around 1000BCE, and in South America more than 1500 years later. In contrast, the first cities in Asia were built more than 10,000 years ago. I hope this helps explain why the population in some regions began to explode, while elsewhere folks were still living in tiny villages. Here are some useful numbers for comparing all seven continents: Asia: population density 225 per square mile / 87 per sqkm Europe: 180/72 Africa: 80/30 North America: 59/23 South America: 56/21 Australia: 11/4 Antarctica: 0/0
Yet agriculture started in the middle east . Did the out of Africa modern man carry the agricultural technology to China and India ? No, sense there is were the highest population is . the whole Asia is not populated example Siberia , which is a wast territory and is unpopulated
I am white and have an Asian second wife. I'd say that the culture is more loving and conducive to families and intimacy. I was fooled into believing our culture was more family oriented, but go to a park on a Sunday and see how many white families you see gathered. I suppose this may sound racist, but it does seem culturally true. In North American families raise children till they can fend for themselves and ship them out, but many cultures see no shame in having many families under the same roof. For the sake of argument I will add that Asians are more family oriented.
That's about .001 per square mile. They rounded that to zero. Please Register or Log in to view the hidden image!
Like many technologies, agriculture was invented multiple times in multiple places. First in Mesopotamia, then India, China, Egypt, Mesoamerica and the Andes. Probably also in Japan and Vietnam, and perhaps somewhere in Oceania, but it's too difficult to analyze the evidence and be sure. Humans migrated out of Africa 50,000 years ago. (Actually 60,000, but that first group settled in Australia.) Agriculture (farming and animal husbandry) was invented much later, about 12,000 years ago. It was not brought out of Africa; it was invented first in Asia. Agriculture was also invented in what is now the USA, but very late on the time scale, probably no earlier than 2,000 years ago. They had cultivated corn and domesticated turkeys. Agriculture always brings an era of peace because it generates surplus food so people no longer have to fight to survive during bad years. The Native Americans in the eastern part of the continent had established trading networks between the villages over a rather large area. If the Christian armies hadn't arrived with their guns and their syphilis and their smallpox and their attitude, there's no telling what kind of civilization might be here today.
The agriculture of the US was developed in Mexico. Corn, beans, squash, tomato, peppers, and several other plants were domesticated and spread north. The civilizations arising from this were familiar to the Europeans - armies, emperors, trade and tradesmen, priesthoods, arithmetic and writing and hierarchical bureaucracies, etc etc. Peace was established by conquest and expansion of government, made possible by food surplus. Syphilis in its familiar plague form seems to have been endemic to the Americas, and appeared in Europe only after the return of the early Western explorers there, beginning in the port cities the first returning ships docked at.
According to some literature Maize was cultivated in Central America 3400 BC and in Peru 3600 BC . In the region of Peru and Bolivia very sophisticated irrigation existed about 4500 BC.
