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.
How old is the fossil?
The oldest fossil found on earth is 3.5 billion years old
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 does the fossil record help us determine the evoultion of organisms?
The fossil record is life's evolutionary epic that unfolded over four billion years as environmental conditions and genetic potential interacted in accordance with natural selection. It shows us the changes species have incurred over millions of years.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.
How many years ago were protists first found in the fossil record?
1.8 billion years ago
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.
How old are the oldest fossils of bacteria?
Stromatolites have been dated back to as far as 3.4 billion years ago, and are amongst the oldest known fossils found on Earth. Stromatolites are still present today, and can be found in very salty lakes, and marine lagoons.
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.
Fossil evidence indicates that the earliest bacteria on Earth lived about how many years ago?
3.5 to 4 billion years
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.
How long has life been on earth?
