Preservation of organisms over time and across continents provides evidence for common ancestry |
|
|
|
Amber |
Organisms get stuck in plant resin and get encased by it before it hardens |
|
|
|
Permineralization |
Pores of a plant, bones and shells are filled by minerals from the ground, lakes or oceans and then hardens |

|
|

Comparison of developmental stages between organisms provides evidence of common ancestry |
|
|
|

Structures in different species that have the same appearance, structure or function but have evolved separately, thus do not share common ancestor |
|
|
|
Co Evolution |
Two independent species evolving together to meet mutual needs |
|
|
|
