Why anatomical and molecular features often fit a similar nested pattern.in addition descibe a orocess that can cause this not to be the case

Respuesta :

Anatomical and molecular features often fit a similar pattern due to Homology. Homology is the existence of shared ancestry between two structures or genes in a different species. 

A process that can cause this not to be the case is Convergent Evolution.
Convergent Evolution occurs when two unrelated species independently evolve similar traits to cope with evolutionary changes.
