Why is it all living things originated from a common or universal ancestor?

Because we can trace the genetic trail back that far and the fossil trail almost back that far. One genetic code shared by all organisms is rather good implicating evidence for universal common ancestor.

Almost all living organisms use DNA ATP and the same DNA triplet code this is an example of evolution based on what?
Common ancestry. In this case the last universal common ancestor, LUCA.
How is it possible that 20 million living organisms on the planet are made up of only 5 types of nucleotide bases arranged in long chains?
Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
Which living organism most resemble the common ancestor of all life according to genetic testing?
organisms living deep in the oceans around seafloor volcanic vents and in hot springs
What best describes the theroy of evolution?
It describes via what mechanism modern life forms derived from their common ancestors.
What are the structurall and biochemical similarities of animalsand all living organisms?
The structural and biochemical similarities among living organisms are best explained by Darwin's conclusion: Living organisms evolved through a gradual modification of earlier forms --- descent from a common ancestor.
Do all living things have a common ancester?
Yes. Go far enough back and we can posit a universal common ancestor.
What is the name of the first living thing on earth?
There is no particular name for it, since we do not know exactly what that organism was. We do, however, have a general name LUCA, which stands for Last Universal Common Ancestor, meaning the last living thing that was the ancestor of all life on Earth.

Common ancestry. In this case the last universal common ancestor, LUCA.
Is it rue that humans have not descended from chimpanzees but do have a common ancestor with them?
Yes, that's correct. Humans and chimpanzees share a common ancestor that lived several million years ago. While humans and chimpanzees have diverged along separate evolutionary paths since then, they still share a significant amount of genetic material due to their common ancestry.
Who was it that proposed that all living things came from a common ancestor?
Charles Darwin
What is ramaphitecus?
The common ancestor of Homo with the other living Great Apes must be even older.
How is it possible that 20 million living organisms on the planet are made up of 5 types of nucleotide bases arranged in long chains?
Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
Where cheetahs originated from?
The current scientific consensus is that cheetahs evolved between 26 and 7.5 million years ago in Africa; however, genetic analysis shows that the common ancestor of all living cheetahs lived in Asia about 11 million years ago.
What are clades A clade is a group of organisms consisting of a common ancestor and all its descendants But doesn't every living thing have a common ancestor Please help Thanks?
Yes, all living things are just groups of organisms consisting of common ancestors and all their decendant's. Clades is just a word that means a group of organisms.
How is it possible that 20 million living organisms on the planet are made up of only 5 types of nucleotide bases arranged in long chains?
Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
What are connected to cheetahs?
The cougar is the closest living relative of the cheetah. They both evolved in North America from a common ancestor.
What is the phenomenon called when the similarity of the characteristics of sheep and reindeer is due to their having a common ancestor?
The similarity of sheep and reindeer is due to parallel evolution. This is when two species have a common ancestor and have developed similar traits, despite living in different areas.
