Flagella might have arisen through the ingestion of which of the following?

Correct answer: D. Spirochetes

  • A. Cyanobacteria
  • B. Chlamydomonas
  • C. Paramecium
  • D. Spirochetes

Explanation

The flagella might have arisen through the ingestion of spirochetes, which are spiral-shaped bacteria. Spirochetes are motile, meaning that they can move around, and they have flagella that help them to do this. Cyanobacteria, Chlamydomonas, and Paramecium are all eukaryotes (organisms with a nucleus). Eukaryotes did not evolve from prokaryotes.

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.
