## Step 1The question is asking about the observations made by Charles Darwin related to biogeography and its role in species evolution. Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.## Step 2Charles Darwin, a renowned biologist, made several observations that have significantly contributed to our understanding of evolution. Two of these observations are particularly relevant to this question:### **Observation 1**: Species that are closely related can evolve diverse adaptations in slightly different environments.This observation is based on Darwin's studies of finches on the Galapagos Islands. He noticed that while the finches were closely related, they had evolved different beak shapes and sizes, each adapted to a specific type of food source available on different islands. This is an example of adaptive radiation, where species diversify rapidly from an ancestral species into a variety of forms to fill different ecological niches.### **Observation 2**: Species that are distantly related can evolve similar adaptations in similar environments.This observation is based on Darwin's studies of the similar adaptations of marsupials in Australia and placental mammals in South America. Despite being from different lineages, these species have evolved similar traits due to similar environmental pressures. This is an example of convergent evolution, where unrelated species independently evolve similar traits as they adapt to similar environments or ecological niches.## Step 3Based on these observations, the correct answers are B and D. Option B reflects Darwin's observation of closely related species evolving diverse adaptations in slightly different environments, while option D reflects his observation of distantly related species evolving similar adaptations in similar environments.
