Our best evidence to data suggests that the Earth formed 4.6 billion years ago. What life forms
existed on Earth during the following periods. (Match the correct answer to each question; you
may use each answer more than once.) What happened during the first billion years (4.5-3.6
billion years ago)? What happened during the second billion years (3.6-2.6 billion years ago)?
What happened during the third billion years (2.6-1.6 billion years ago)? What happened during
the third billion years (2.6-1.6 billion years ago)? What happened during the fourth billion years
(1.6-0.6 billion years ago)? What happened during the last 600 million years (0.6 billion years
ago to present)? A. no life existed B. unicellular life appeared C. unicellular life forms were the
only living things on Earth d. multicellular life appeared. E. dinosaurs dominated the entire
period F. mammals dominated the entire period
Solution
What happened during the first billion years? (4.6 -3.6 billion years ago?) A. no life existed.
Reason: Earth was formed over 4.6 billion years ago.Before that there was no life.
What happened during the second billion years? (3.6 -2.6 billion years ago?) C.Unicellular life
forms were the only living things on earth.
Reason:Unicellular life appeared first about 3.6 billion years ago.
What happened during the third billion years? (2.6-1.6 billion years ago?) B.unicellular life
appeared.
Reason:Unicellualr life appeared on earth during this period.
What happened during the fourth billion years? (1.6 -0.6 billion years ago?) D.multicellular life
appeared.
Reason:Multicellular life appeared 1.5 billion years ago.
What happened during the last 600 million years (0.6 billion years ago to pesent?) E and F.
Dinosaurs dominated the entire period and mammals dominated the entire period.
Reason: Both dinosaurs and mammals appeared in this period .Dinosaurs appeared first and then
