Question 16
Convergent evolution may produce similar structures in two different species. This may lead to A. analogy. B. homology. C. divergence. D. embryology.
Worked Solution & Example Answer:Convergent evolution may produce similar structures in two different species - VCE - SSCE Biology - Question 16 - 2004 - Paper 1
Step 1
This may lead to - A. analogy.
Answer
Convergent evolution is a process through which unrelated or distantly related organisms develop similar traits or structures due to adapting to similar environments or ecological niches. This results in analogous structures, which are similar in function and appearance but do not share a common ancestry. Examples include the wings of bats and birds, which serve the same function but evolved independently.
Step 2
This may lead to - B. homology.
Answer
Homology refers to similarities resulting from shared ancestry, where structures retain a similar form despite differing functions. For example, the forelimbs of mammals, birds, and reptiles share a common structural format despite serving different purposes.
Step 3
This may lead to - C. divergence.
Answer
Divergence occurs when two or more related species evolve different traits and structures as they adapt to different environments or ecological niches over time. This process leads to increased differences between species that share a common ancestor.
