The presence of similar but distinct species on neighboring islands suggests
- Acheck_circle
Common ancestor that arrived once and then diverged after isolation
- B
Independent origin on each island without any shared evolutionary history
- C
Recent hybridization across islands producing nearly identical species
- D
Convergent evolution from unrelated ancestors that colonized each island
Explanation
Vicariance and dispersal followed by allopatric speciation explain such patterns (e.g., Galápagos and Hawaiian island species).
