Which answer best describes the most widely held theory about how humans came to populate Earth?
The most widely held theory about how humans came to populate Earth is the Out of Africa theory. This theory suggests that early humans originated in Africa and then migrated to other parts of the world, eventually replacing other hominid species such as Neanderthals. Genetic and fossil evidence support this theory.

What was The most widely accepted theory among scientists is that the last place humans migrated to was?
The most widely accepted theory among scientists is that the last place humans migrated to was the Americas, crossing the Bering land bridge from Asia between 15,000 and 20,000 years ago.
What is the name of the scientist that came up with the theory of plate tectonic?
Alfred Wegener is the scientist credited with proposing the theory of plate tectonics in 1912, although his ideas were not widely accepted until later.
Who is the scientists responsible for the flat earth theory?
There is no legitimate scientist responsible for promoting the flat earth theory. The idea of a flat earth has been widely discredited by centuries of scientific evidence and research.
When and why did Alfred's theory become accepted?
Alfred Wegener's theory of continental drift, proposed in the early 20th century, became widely accepted in the 1960s after additional evidence supporting it was discovered, including seafloor spreading and the existence of magnetic striping on the ocean floor. This evidence provided a mechanism for how continents could move and led to the development of the theory of plate tectonics, which is now widely accepted in the scientific community.
What did scientist believe before Continental Drift?
Before the theory of Continental Drift was widely accepted, scientists believed in the concept of stationary continents. They thought that the continents were fixed in place and did not move over time. This idea was known as the theory of continental permanence.
Where do experts think beings originated?
Experts believe that beings, particularly humans, originated in Africa, where early hominins evolved. The "Out of Africa" theory suggests that modern humans migrated from Africa to populate other parts of the world around 60,000 to 80,000 years ago. This theory is supported by fossil evidence and genetic studies that trace the lineage of contemporary humans back to a common ancestral group in Africa. Other theories exist, but the African origin remains the most widely accepted among scientists.
What was The most widely accepted theory among scientists is that the last place humans migrated to was?
The most widely accepted theory among scientists is that the last place humans migrated to was the Americas, crossing the Bering land bridge from Asia between 15,000 and 20,000 years ago.
What theory describes an acid as a proton and a base as a proton acceptor?
The theory that describes an acid as a proton donor and a base as a proton acceptor is the Brønsted-Lowry acid-base theory. In this theory, an acid is defined as a species that donates a proton (H+), while a base is a species that accepts a proton. This theory is widely used in understanding and predicting acid-base reactions.
Which term describes a scientific idea that has been supported by many different experiments?
The term that describes a scientific idea supported by many different experiments is a "theory." In the scientific context, a theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has withstood extensive testing and scrutiny. Unlike a hypothesis, which is a tentative explanation, a theory is widely accepted due to its robustness and reliability.
What is the most widely accepted theory of the earliest human migration to the Americas?
The most widely accepted theory of the earliest human migration to the Americas is the Beringia Land Bridge hypothesis. This theory posits that ancient humans crossed a land bridge that connected Siberia and Alaska during the last Ice Age, around 20,000 to 30,000 years ago. From there, they migrated southwards through North and South America.
What is one accepted theory about how humans made their way to the Americas?
The most widely accepted theory is that humans migrated to the Americas via a land bridge called Beringia that existed during the last Ice Age, connecting Asia and North America. This migration is believed to have occurred around 15,000-20,000 years ago, with early humans following game animals and moving southwards as the ice sheets receded.
What Terms best describes a conceptual scheme in science that is strongly supported has not yet been found incorrect and is based on the results of many observations?
The term that best describes such a conceptual scheme in science is a "theory." A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has withstood extensive testing and scrutiny. While it is not an absolute truth, a scientific theory is robust and widely accepted due to its strong empirical support and consistency with observed phenomena.
What is the difference between classical set theory and fuzzy set theory?
Classical theory is a reference to established theory. Fuzzy set theory is a reference to theories that are not widely accepted.
What scientific is well tested and widely accepted view that scientists agree best explains certain observable facts?
The answer is a theory. A view that is not well-tested and widely accepted is just a hypothesis. A law has to be indisputable not just widely accepted
Who is widely considered to be the father of atomic theory?
John Dalton
A hypothesis that is widely accepted as correct?
It may become a theory.
What is a well tested scientific idea that is widely accepted?
theory
