Flagella must have arisen through the ingestion of:
Correct answer: D. Spirochetes
- A. Cyanobacteria
- B. Chlamydomonas
- C. Paramecium
- D. Spirochetes
Explanation
Flagella are thought to have evolved through the endosymbiotic relationship where certain bacteria, like spirochetes, were incorporated into early eukaryotic cells. The spiral shape and flagella of spirochetes contributed to the development of flagella in eukaryotes. Other organisms listed, such as Cyanobacteria, Chlamydomonas, and Paramecium, do not play a direct role in the evolutionary origin of eukaryotic flagella.

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.
