| Statement I: | Adaptive radiation within different isolated environments (such as separate lakes) can lead to convergent evolution when species independently evolve similar traits to adapt to similar ecological niches. |
| Statement II: | This convergence occurs despite the species having different evolutionary histories, highlighting how similar environmental challenges can shape similar evolutionary outcomes. |
