- Patterns in the fossil record
- Pattern of Anatomical Similarities
- Pattern of Embryological Similarities
Anatomical Evidence:
-
Homologous: common ancestor, same structures.
-
Analogous: no common ancestor, but same structure.
-
Fossil Evidence:
-
-
Transitional Form: organisms that show the intermediate states between an ancestral form and that of its descendants.
Change in population over time, not a change in an individual.
Population: group of individuals of the same species that live in the same area and reproduce with one another.
-
Adaptive Radiation: species are distinct from another, but are closely related.
