The actual remains or traces of organisms that lived in ancient geological times are known as:
Correct answer: C. Fossils
- A. Vestigial organs
- B. Fuel
- C. Fossils
- D. All of these options are correct
Explanation
OPTION A: Vestigial organs are organs, tissues, or cells in a body that are no longer functional the way they were in their ancestral form of the trait. OPTION B: Fuel is a material used to produce heat or power by burning. OPTION C: Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossils include shells, bones, stone imprints of animals or microbes, and exoskeletons. Hence, C is the correct option. OPTION D: It is an incorrect option.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
