How old was earth when life appeared on it?
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
Why didn't oxygen begin to accumulate in the atmosphere until approximately 1.5 billion years after life appeared on Earth?
Oxygen was removed from the atmosphere by chemical reactions with surface rocks as quickly as it was released by life
The time in which life first evolved on Earth was the?
eff the time in wich life first evolved on earth!!
The earth is approximately 4600 million years old life has been on earth more or 500 million years Name two conditions that would have made living on the earth difficult in the first couple of million?
The Earth was not inhabitable for the first billion years because it was cooling off. When our solar system drifted from the Sagittarius Arm and was out in the open, the radiation from our sun was much more intense and life went crazy, i.e.: the Cambrian Era. There was also no oxygen until after plant life came about and produced it. Then animals and fungi emerged, thrived, and evolved.
When did life originate on earth?
Life first evolved when God created animals during creation. Human life began shortly thereafter on the sixth day. Ever since then, men have been born and living just as they did when the earth beganAnswer:The Earth itself formed some 4.5 billion years ago. Less than 700 million years after that (3.8 billion years ago) the first microbial life was present in the Earth's water. Evolution began at the same time as these primitive life forms took advantage of the specific environments they were best suited for.Both of these answers are good, but they are based on the Evolution Theory and the Christian's way of believing. Nobody has a real answer for this question, because our little archeologists' machines can't get a good read on anything that far back in history. You have asked a question that even scientists can't directly answer.
When did life first begin?
There is evidence of life on Earth since around 3.7 billion years ago.
Where did life begin?
Life first began in the Earth's oceans, a few billion years ago. and cave men came from monkeys.
How many years ago did life on earth begin?
4.567 million years ago
When did life on earth begin to evolve?
Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis. If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies. See related links. Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.
What era was when life first flourished on Earth?

you did
When was first species on earth?
Scientific AnswerThe first bacterial life to appear on Earth was 3.46 billion years ago in the Precambian supereon. The first complex life appeared around 600 million years ago just preceding the Cambrian Explosion of life 530 million years ago.
