Shows distantly related species can evolve similar adaptations if they live in similar environments

|
Natural selection in similar habitats led to similar adaptations

Shows how various structures across different species have the same function but have evolved separately

Detailed explanation-1: -Biogeographical patterns provide clues about how species, both alive and extinct, are related to each other. The fossil record, though incomplete, provides valuable information about what species existed at particular times in Earth’s history.
Detailed explanation-2: -Broadly, the theory of evolution is supported by biogeography through evidence such as the species on Earth being distributed around the planet based on their genetic relationships to each other.
Detailed explanation-3: -Answers may include that DNA sequencing provides a new way to identify evolutionary relationships among species, including relationships that are not as obvious from just physical and behavioral traits. For example, DNA evidence can give us a better idea of which species diverged from common ancestors.
Detailed explanation-4: -How is biogeography useful for identifying evolutionary relationship? It is useful because the patterns in the distribution of fossils and living species and with the information given from geology that tells us how they evolved.
