Cladogram
|
A tree-shaped diagram showing evolutionary relationships and the points where species appear to have diverged from common ancestors
|
|
|
Coevolution
|
When two organisms evolve to have traits that accentuate each others needs.
|
|
|
Homologous Structures
|
Homologous structures are body parts that are alike because the species in question share a common ancestor.
|
|
|
