What was the reason for the early prolonged absence of humans in the Western Hemisphere?
Wiki User
∙ 10y ago
The early prolonged absence of humans in the Western Hemisphere can be attributed to geographical barriers such as vast oceans that made long-distance travel challenging for ancient civilizations. Additionally, the lack of advanced navigation technology and seafaring skills likely limited early human migrations to the Western Hemisphere.

What is the basic reason for the early prolonged absence of humans in the western hemisphere is?
The early prolonged absence of humans in the western hemisphere is primarily attributed to geographical barriers, such as vast oceans, that limited travel and migration from other continents. This isolation led to the development of distinct ecosystems and cultures in the Americas before the arrival of European explorers.
What will be the chance of human evolution in the absence of monkey?
None. Humans are per definition both the descendants of monkeys and monkeys themselves. Had monkeys not evolved, then man could not have evolved, anymore than a grandson can exist whose grandparents did not.
When did our human species leave Africa?
Our human species, homo sapiens, lived exclusively in Africa up until about 100,000 years ago. Only about 1,000 centuries ago did the first humans leave Africa. Many legends (including the Book of Exodus in the Bible) refer to humans leaving Africa and the fossil record provides evidence that this occurred not so long ago, in evolutionary terms (and timelines). The consensus among paleontologists is that humans left Africa from the region of Egypt, crossing the Sinai peninsula into what is now known as the Middle East. From there, humans spread out into Anatolia (modern day Turkey), Europe and Asia. Approximately 15,000 to 20,000 years ago, humans reached the western hemisphere. North America could be entered via the Bering Straits land-ice bridge (during the last ice age) and humans gradually traveled all the way to the southern portion of South America. Other postulated ways in which humans may have reached South America have included seafaring across the Pacific Ocean. At any rate, since divergent paths were estimated to have been taken by humans and great apes approximately 7 million years ago, it is only relatively recently that humans left their original habitat - in Africa - just 100,000 years ago.
Which kingdom do humans belong?
Humans belong to the mammal group because humans and mammals give milk to there young and they have fur
What is the specific name for humans?
The specific name for humans is Homo sapiens.

Why did immigrants come to us?
We are all immigrants. Humans are not native to the Western Hemisphere.
Why is Antarctica in both the eastern hemisphere and the Western Hemisphere?
Antarctica is in both the eastern AND western hemispheres, and in the southern, of course.Another AnswerAs to 'why', the answer is simply that the lines drawn by humans over the earth separating hemispheres happen to bisect this continent.
What has fossil evidence revealed as the earliest date of human existence in the Western Hemisphere?
To date, fossil evidence shows that humans existed in the Western Hemisphere as far back as 10,000 BC BCE. There is also evidence of tools that also match the fossil remains.
How do human actions affect the Western Hemisphere?
Human actions such as deforestation, urbanization, and industrial activities have significant impacts on the Western Hemisphere including habitat destruction, environmental degradation, and climate change. These actions can lead to loss of biodiversity, water pollution, and disrupt ecosystems, ultimately affecting the health and well-being of both humans and wildlife in the region.
What are the symptoms in the absence of vitamin E and vitamin K?
The abscence of vitamin E (the generic name for all tocol and tocotrienol derivatives that exhibit qualitatively the biological activity of alpha-tocopherol) is a rare event in humans, but is characterized by peripheral neuropathy and spinocerebellar ataxia.The absence of vitamin K (a generic name for 2-methyl-1,4-naphthoquinone and all of its derivatives) causes a prolonged clotting times and hemorrhagic disease.
How did humans migrate to Americas and Oceania from eastern hemisphere?
Land bridges
What are two ways that humans can make soil unproductive?
Soil can be made unproductive by salinification (which is often the result of prolonged irrigation) or by depletion of needed mineral content (after prolonged farming, without fertilization).
How did humans get to the western hemisphere?
This person who wrote this is 100% wrong. Pangea was gone millions of years before this. The real way people got to the western hemisphere is the Earth temperature got much colder (ice age) and when water freezes it contracts. In doing so it exposed a strip of land called the bering strait which is how people crossed. Earths temperatures have heated up since then and it is no longer visible, but if we were to have another ice age it would be.

Absence or presence of humans
What is the reason for the early prolonged absence of humans in the Western Hemisphere?
There was no way for humans to migrate there until the Ice Age made crossing the Bering Sea possible, when worldwide glaciation lowered the sea level. --- The Americas had already separated from the other continents at the time true humans appeared on the Earth, circa 60,000 to 200,000 years ago. It has long been believed that the spread of humans was from Africa to Asia to Europe, and was governed by the colder climates of the Ice Age. When sea levels fell during the last Ice Age, a land bridge existed from Asia through Siberia to North America (around 13,000 to 20,000 years ago). The descendants of Asian immigrants became the American Indian tribes. However, there is some archaeological evidence that humans may have been in the Americas much earlier, as early as 50,000 years ago. Possible explanations include earlier-than-postulated sea voyages from Polynesia. Polynesians are thought to have traveled to South America in the 11th or 12 century AD, around the same time as early voyages to North America by Vikings from Europe.
Does the space station have to fill up with air or oxygen?
It is filled with air, as prolonged exposure to pure oxygen is harmful to humans.
