The earliest fossils known are in the form of stromatolites formed by cyanobacteria about 3.5 billion years ago.
To say however that these are the first life forms is not likely to be correct. Cyanobacteria are already a relatively complex single celled organism. It is likely that simpler forms preceded them but so far no evidence of this has been found.

How does Edmund Locard's Exchange Principle apply to forensic science?
Dr. Locard was the first Forensic Scientist. His theory was that anytime a person comes into contact with anything, they leave silent evidence that they were there. The suspect of a crime will leave evidence that he was there, and like wise, he will take evidence with him.
What is an unaltered fossil?
It's when the rock dies and is attacked by decomposers. This is why it has a small chance of becoming a fossil, but if it does, it gets covered by sediment where it slowly starts to decay. The rock then starts to be preserved where the first layer of sediment is compressed by the weight.
Abundant fossil evidence did not appear in the geologic record until what geologic era?
Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
How do you use evidence in a example?
To use evidence in an example, first, introduce a claim or assertion you want to support. Then, provide specific evidence—such as statistics, quotes, or research findings—that directly backs up your claim. Finally, explain how this evidence reinforces your point, making the connection clear to your audience. This structured approach enhances the credibility and persuasiveness of your argument.
Difference between physical evidence and circumstantial evidence?
Physical evidence usually involves objects found at the scene of a crime. Physical evidence may consist of all sorts of prints such as fingerprints, footprints, handprints, DNA material, cut marks, tool marks, etc.Circumstantial evidence is indirect evidence which creates an inference from which a fact may be concluded. For example, circumstantial evidence of a murder is not based on first-hand eyewitness accounts, but may consist of threats that were made, fingerprints left at the crime scene, or the presence of the accused in the vicinity of the crime.
Who is credited with discovering the first fossilized Australopithecine skull?
The first fossilized Australopithecine skull, known as the Taung Child, was discovered by Raymond Dart in 1924 in Taung, South Africa. Dart's identification of the skull as belonging to a previously unknown species contributed significantly to our understanding of human evolution, providing evidence of early hominins. This discovery was pivotal in the field of paleoanthropology, highlighting the importance of Africa in the origins of human ancestors.
How many years did earth exist before there was evidence of life on?
Earth is estimated to be around 4.6 billion years old, and evidence of the first life forms dates back to about 3.5 billion years ago, in the form of fossilized microorganisms. This means there were around 1.1 billion years of Earth's existence before evidence of life appeared.
The first fossilized eukaryotes date to about how many years ago?
2.1 billion
What is the first thing that must happen before an organism becomes fossilized?
It must die.
In what circumstances recourse to circumstantial evidence is permitted?
Direct evidence, such as eyewitness testimony, is generally considered more powerful, but successful criminal prosecutions often rely largely on circmstantial evidence, and civil charges are frequently based on circumstantial or indirect evidence. When circumstantial evidence is cumulative, the weakness of such circumstntial evidence is strengthened.Circumstantial evidence is indirect evidence which creates a situation from which a main fact may be inferred. For example; in a murder trial there may not be direct evidence based on first-hand eyewitness accounts of the actual murder itself, but the circumstantial evidence may consist of threats made, fingerprints at the crime scene, or the presence of the accused at, or in the vicinity of, the crime.
What was the first ever kind of shark in the world?
