Correct Answer: Option 3 – many organisms that lived on earth have become extinct

Fossil evidences when compared to the species of existing organisms show that the organisms which lived earlier have become extinct now.

Fossil evidence shows that life has evolved from simple to complex forms and mammals developed later than the Precambrian time period. Hence, options 1, 2 and 4 are incorrect.
