Answer:
The correct answer is d.
Species in widely separated but similar biomes often appear to display similar characteristics because of convergent evolution.
Step-by-step explanation:
Convergent evolution is called the evolutionary process from which two types of organisms totally unrelated to each other evolve to similar structures (they are morphologically similar as a whole or in parts) for a purpose, that is, they have adapted to means or similar ecological niches. Convergent evolution is manifested by the presence of similar or equal structures in species that belong to different evolutionary lines (they do not share a common ancestor).
