How many years ago did the first simple cell appear on earth according to most scientific models?
Most scientific models suggest that the first simple cells appeared on Earth around 3.5 to 4 billion years ago. These simple cells evolved into more complex life forms over millions of years through processes like natural selection and genetic mutation.
How old are living things?
Simple life forms like bacteria have on the Earth for about 3,500,000,000 years ago (3.5 billion years). Evidence of this was found in very old rocks in Australia. The estimated age of the earth is 4.5 billion years so life originated just 1 billion years after the earth formed.
When did the first marine plants appear on earth?
the first plants appeared about 3000 years ago. the first plant was algae.
Did life exist 1.7 billion years ago?
Yes, life is believed to have existed 1.7 billion years ago based on fossil evidence of simple organisms like bacteria and algae. This period is known as the Mesoproterozoic era and marks an important time in Earth's history in terms of the evolution of early life forms.
What organism appeared first?
The first single-celled organisms, like bacteria, are believed to have appeared around 3.5 billion years ago. These organisms are considered some of the earliest forms of life on Earth.

How many years ago was the first plant on earth?
The first cells emerged about 3 billion years ago, and about 1 billion years later, the first plant-like things came about, though they didn't really resemble current day plants. They were exclusively underwater and weren't as adapt to their environment as they are today.

What plants were on the earth 4.6 billion years ago?
It is believed that the Earth was still in a molten state 4.6 billion years ago, so there were no plants or any other complex life forms on the planet at that time. The first evidence of simple life forms appeared around 3.5 billion years ago.
When did the first marine plants appear on earth?
the first plants appeared about 3000 years ago. the first plant was algae.
What were probably the first living things?
The first living things on Earth were likely single-celled organisms such as prokaryotes, like bacteria and archaea. They appeared around 3.5 to 3.8 billion years ago in early Earth's oceans.
Did life exist 1.7 billion years ago?
Yes, life is believed to have existed 1.7 billion years ago based on fossil evidence of simple organisms like bacteria and algae. This period is known as the Mesoproterozoic era and marks an important time in Earth's history in terms of the evolution of early life forms.
How long will a star like earth's sun last?
13 billion years, roughly. Our sun was created about 6.5 billion years ago so it is just starting middle-age.
What species aperd on earth frist?
The first known species to appear on Earth were single-celled microorganisms like bacteria and archaea. These simple life forms emerged around 3.5 billion years ago.
What is percanbrian?
If you mean precambrian? It is an epoc in the earth's history. Something like 4 billion years ago.
What was life like at the beginning of earthHow is that different from life now?
When the Earth was formed, there was no life for a billion years.
When did life first appear in the Earth's ocean?
Life is believed to have first appeared in Earth's oceans around 3.5 billion years ago. This was in the form of single-celled organisms like bacteria and archaea. These early life forms were the foundation for all subsequent life on Earth.
