Not all scientist believe this, because some scientist can think and know that the chances of the beauty of the design we see in the world all around us, wither man made or of nature, is absolutely impossible.

They are more chances that a Rolls-Royce on any showroom floor came from the back of a cement mixer full of all the right parts, than there are that a "single-celled ancestor" evolved into the complex world around us.

Why do most scientists believe that all life on earth evolved from a single-called ancestor?

Scientists believe in the theory of universal common ancestry because of evidence like the genetic code shared by all living organisms, similarities in biochemical processes, and the fossil record showing the progression of life forms over time. This theory provides a coherent explanation for the diversity and unity of life on Earth.


Why do scientist believe that all life on earth evolved from a singe celled ancestor?

Scientists believe that all life on Earth evolved from a single-celled ancestor because of the similarities found in the genetic code and cellular structure of all living organisms. This suggests a common origin and shared ancestry. Additionally, the gradual changes observed in the fossil record and the patterns of biodiversity support the idea of evolution from a common ancestor.


What did scientists think life evolved from?

Scientists believe that life on Earth evolved from simple molecules such as amino acids and nucleotides that formed in early Earth's environment. These molecules gradually combined and evolved to form more complex molecules and eventually led to the emergence of living organisms. This process likely occurred over millions of years through a series of chemical reactions.

Why do most scientist believe that all life on earth evolved from a single-felled ancestor?

Scientists believe in the theory of universal common descent because it provides a coherent explanation for the diversity of life on Earth. Evidence from various fields such as genetics, biochemistry, and the fossil record supports the idea that all living organisms share a common ancestor. Additionally, the theory has successfully predicted and explained many observations in the biological world.

Do scientists believe man was created by God or that they just evolved?

Different scientists hold different beliefs. Many scientists accept the theory of evolution as a scientific explanation for the diversity of life on Earth. However, there are also scientists who believe in theistic evolution, which posits that evolution is a process guided by a higher power, such as God. Ultimately, beliefs about the origins of humans vary among scientists.


How long have paramecium been on earth?

Paramecium are single-celled organisms that were first discovered in the 17th century. Scientists believe paramecium have been around since the Earth was formed.

What molecule do scientists believe came first in the evolution of life on Earth?

Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).


Do scientists know how DNA evolved?

In the theory of how life began, scientists have theorized that DNA evolved through natural selection. The challenge remains to develop a theory to explain how RNA developed from the primordial soup which scientists believe constituted the Earth's surface 3.8 billion years ago. Did evolution start in space, in oceans, salt pans, volcanic exhalatives or in underground cavities?
