Answer
The pattern of phylogeny for the American mole and Australian marsupial mole is an example of convergent evolution.
Solution
a
Convergent Evolution: This occurs when different species evolve similar traits independently, often because they adapt to similar environments or ecological niches
b
Different Ancestors: Despite their similar burrowing structures, the American mole and Australian marsupial mole have different non-burrowing ancestors, indicating that their similarities are not due to a common ancestor but rather to similar selective pressures
Key Concept
Convergent Evolution
Explanation
Convergent evolution explains how different species can develop similar traits independently due to similar environmental pressures, despite having different ancestral origins.
