What is any naturally preserved evidence of life?
Fossilised ancient life-forms. There are even fossilsed bacteria from 30 billion years ago.
How long ago did multicellular life forms appear in the fossil record?
According to the fossil record, multicellular life forms first appeared about 570 million years ago. This means multicellular organisms appeared almost 3 billion years after the first evidence of life.
Planetary geologists used meteorite dating and lunar rocks to determine that?
the solar system is 4.6 billion years old.
The first organisms evolved on Earth around 4 billion years ago The fossil record indicates that the first organisms were?
a. marine invertebrates b.land plants c.reptiles d.prokaryotes
When did life on earth begin?
The earth began to be formed over 4.5 billion years ago,but for millions of years nothing could live here.Gradually,the earth's crust and the atmosphere formed.The simplest form of life, bacteria and algae,probably began to grow less than four billion years ago.Human beings did not appear until about two million years ago.
The fossil record indicates that the earliest cells lived about?
According to the fossil record, the earliest cells lived about 3.5 billion years ago.
Do fossil records indicate there has been life on earth for 6 billion years?
A:No. The earliest evidence of life on earth is probably less than 3 billion years. The earth itself is only about 4.5 billion years old.
How old is the fossil?
The oldest fossil found on earth is 3.5 billion years old
How many years ago were protists first found in the fossil record?
Protists were first found in the fossil record around 2.1 billion years ago.
What is the age of the oldest fossil on record?
The age of the oldest fossil on record is about 3.5 billion years old.
What is the age of the oldest fossil you have dated?
The oldest fossil that has been dated is approximately 3.5 billion years old.
What year will it be in 4 billion years?
To determine the year in 4 billion years, you start with the current year, which is 2023. Adding 4 billion years to this gives you 4,000,002,023. Therefore, in 4 billion years, it will be the year 4,000,002,023.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.
How do geologist know that the earth is 4.6 billion years old?
Geologists determine the age of the Earth by studying radioactive decay of certain elements in rocks and meteorites, such as uranium to lead. By measuring the ratios of these radioactive elements and their decay products, scientists can calculate the age of Earth to be approximately 4.6 billion years. This method is known as radiometric dating.
Is the fossil complete?
No, the fossil record is not complete. Not all animals and plants were fossilized during the last 4 billion years of the earths existence.
The oldest fossil organism found lived approximately how many years ago?
The oldest fossil organism found lived approximately 3.5 billion years ago. The fossil is that of a single-celled organism called Archaea.
Is the fossil record complete?
No, the fossil record is not complete. Not all animals and plants were fossilized during the last 4 billion years of the earths existence.
