That depend on your religion. Some religions believe that people were. But if you go for evolution, then its single celled organisms.
The fossils of the oldest life forms can be found in the Precambrian period of the fossil record.
Adam and Eve :)
SOMETHING haha i got you hehehahahoho
The oldest forms of life are found in the kingdoms Archaea and Bacteria. These are both prokaryotic organisms that have been on Earth for billions of years. They are known for their resilience and adaptability to extreme environments.
It is so because, the oldest fossils are obtained from the life forms which used to exist at that time in the oldest ages. At that time there was no so much changes in the world, the life forms being simpler. As the age of the earth advanced hence the forms of life also adapted or tried to adapt to the changes of the surrounding. The climate changed and so did the life forms. It was determined that in the older times, 1st life forms came in the water bodies and then from there the land forms developed. So as we see the later life forms are more complicated, thus the oldest fossils are more simpler compared to their most recent counterparts.
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
Single celled organisms like a bacteria and are some of Earth's oldest life forms.
The oldest organisms in the world are still alive today. Their domain is called archaea. Archaebacteria were the very first life forms on Earth. They are single-celled and their cells have no nuclei. They reproduce asexually. Hope this helped!
The oldest fossil in the world is significant because it provides valuable information about the earliest forms of life on Earth. By studying this fossil, scientists can learn about the evolution of life and how it has changed over billions of years. This helps us understand the origins and development of life on our planet.
The oldest fossils are significant because they provide clues about the earliest forms of life on Earth, helping scientists understand the evolution and diversity of life over billions of years. These fossils offer insights into the conditions of the ancient Earth and the processes that shaped life as we know it today.
1. Contains some of the oldest forms of life on earth2. All are single celled organisms3. Can be found on or in the body4. Do not have a nucleus
Words with -est at the end are called "superlative" forms. The word "oldest" is an adjective.
