The evolutionary view of biogeography predicts that contemporary armadillos are modified descendants of earlier species that occupied:
Correct answer: D. South America
- A. Asia
- B. Neighboring continents
- C. Other continents
- D. South America
Explanation
The evolutionary view of biogeography suggests that species evolve in the regions they currently inhabit, supported by historical presence and gradual adaptation. Thus, contemporary armadillos are considered modified descendants of species that occupied the same continents, specifically the Americas. This aligns with biogeographical evidence and the principle that species evolve in their current geographical locations rather than originating from distant or other continents. The incorrect options suggest origins from regions outside of their current habitat, which contradicts the evolutionary theory of biogeography.

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.
