Question

Prehistoric forms of life are found in fossils. The probability of finding fossils of more complex organisms

• A. Increases from lower to upper strata
• B. Decreases from lower to upper strata
• C. Remains constant in each stratum
• D. Uncertain

Answer 1

The correct option is A Increases from lower to upper strata

The evolution results in the development of the organisms which are more advanced and complex compared to the older ones. The fossils are formed due to the dead remains of the organisms under the layers of soil. The more complex organism will be most found in the upper layers and so the fossils will increase in the complexity from lower to upper.

Thus, the correct answer is option A.
