Question

Which of the following correctly lists the order of important first events in the history of life?

1) Formation of Earth, Origin of Life, Evolution of Prokaryotes, Evolution of Eukaryotes
2) Origin of Life, Formation of Earth, Evolution of Prokaryotes, Evolution of Eukaryotes
3) Formation of Earth, Evolution of Prokaryotes, Origin of Life, Evolution of Eukaryotes
4) Origin of Life, Evolution of Prokaryotes, Formation of Earth, Evolution of Eukaryotes

Answer 1

The correct order of major life events on Earth is: Formation of Earth, Origin of Life, Evolution of Prokaryotes, and Evolution of Eukaryotes, which corresponds to Option 1.

Step-by-step explanation:

Correct Order of Important First Events in the History of Life

The correct order of important first events in the history of life is as follows: Formation of Earth, Origin of Life, Evolution of Prokaryotes, Evolution of Eukaryotes.

This sequence takes into account that Earth formed approximately 4.54 billion years ago. Life's origins date to some 3.7-4.1 billion years ago, starting with the first prokaryotic cells.

It took over a billion years after the formation of Earth for the first life forms to evolve. Eukaryotes, which are more complex cells with a distinct nucleus, did not emerge until about 2.1 billion years ago.

Given these facts, the correct choice in the list of options provided would be Option 1, which correctly lists the chronological order of these significant events leading to the diversity of life as we know it today.
