Patterns of Evolution

Question 1

Explain Divergent evolution

Answer 1

Divergent evolution occurs because of allopatric or sympatric speciation. As time passes, the lineages become increasingly dissimilar to each other but still contain homologous structures due to their common evolutionary origin.

Question 2

Explain Convergent evolution

Answer 2

Convergent evolution describes what happens when two unrelated species that live in similar environments or ways of life evolve similar adaptations to the selection pressures in those environments.

Question 3

What are homoplasies/ analogous features?

Answer 3

Similar features are shared between different species an example is sharks and dolphins.
