Traces of homologous structures; reduced in size.

• Homologous structures

• Vestigial organ

• Artificial selection

• Analogous structure

Survival of the fittest

• Natural selection

• Artificial selection

• Homologous structures

• Analogous structures

Have different mature forms, but develop from same embryonic tissue; example = limbs of reptiles, birds, and mammals

• Homologous structures

• Vestigial organ

• Analogous structure

• Artificial selection

Similar in function, but not in structure; example = wings of a butterfly and wings of a bird.

• Homologous structure

• Vestigial organ

• Artificial selection

• Analogous structure

Nature provides the variation, and humans selected those variations that they find useful.
