Pick the odd one out
Correct answer: D. Psilotum
- A. Psilophyton
- B. Rhynia
- C. Cooksonia
- D. Psilotum
Explanation
Psilophyton, Rhynia and Cooksonia are extinct early vascular plants known mainly from fossils, whereas Psilotum is a living whisk-fern genus. The likely mistake is choosing Cooksonia because it is less familiar, although it belongs to the same early fossil group as the other two.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
