Types of Evolution Evidence Quiz

Structural, DNA, and biogeographical

Homologous structures are similar structures found in different species due to common ancestry. For example, lions, birds, whales, and humans have the same bone structures in their appendages.

Analogous structures evolved independently in different organisms due to similar environments or selective pressures. Unlike homologous structures, they do not indicate common ancestry.
