Question

Compare and contrast convergent and divergent evolution.

Answer 1

Feature	Convergent evolution	Divergent evolution
Definition:	Unrelated species evolve similar traits due to similar environments.	A common ancestor gives rise to species with different traits over time.
Cause:	Comparable environmental selection pressures.	Distinct environmental circumstances or requirements for adaptation.
Example:	Bats and birds both have wings, which are used for flight, but have developed separately.	Darwin’s finches (diverse diets led to the evolution of distinct beak forms from a common ancestor).
Type of structures:	Analogous structures (different origin, same function).	Homologous structures (same origin, different functions).
