Answer

Biogeography supports evolution by confirming traditional classifications based on anatomy, showing how changes in climate affect fossil species, and demonstrating adaptive radiation on isolated islands.

Solution

Biogeography provides several lines of evidence that support the theory of evolution. Here are the correct contributions: 1. **Confirmation of traditional classification based on anatomy**: Biogeographical patterns often align with anatomical classifications, supporting the idea that species with similar anatomical features share common ancestry. 2. **Correlation between changes in climate and fossil species**: Studying the geographical distribution of fossil species in relation to historical climate changes helps scientists understand how species have evolved and adapted over time. 3. **Identification of adaptive radiation on isolated islands**: Isolated environments, such as islands, often exhibit adaptive radiation, where a single ancestral species diversifies into multiple species adapted to different ecological niches. A classic example is the finches on the Galápagos Islands studied by Charles Darwin. **Incorrect Option:** - **Explanation of distribution based solely on habitat adaptations**: While habitat adaptations are important, explaining species distribution solely based on this factor does not encompass the broader biogeographical evidence related to evolutionary processes. **Selected Contributions:** - Confirmation of traditional classification based on anatomy - Correlation between changes in climate and fossil species - Identification of adaptive radiation on isolated islands

Bonus Knowledge

Biogeography paints a colorful picture of how species have evolved in isolation, especially on islands! For instance, the unique species found in the Galápagos Islands, like the famous finches, showcase adaptive radiation. These birds adapted to different environments, leading to various beak shapes and sizes, all originating from a common ancestor. Such vivid examples help us understand how geographical isolation drives evolution by allowing species to diverge based on their surroundings. Moreover, the correlation between changes in climate and fossil species gives us a time machine into the past! When climate shifts, species must adapt, migrate, or face extinction. Fossil records show how certain species thrived or disappeared in response to these environmental changes, providing clear evidence of evolution over time. This connection strengthens the evolutionary narrative, linking living creatures to their ancient relatives and demonstrating how the Earth’s changing face has sculpted life itself.
