ANATOMICAL PROOF OF EVOLUTION AND FOSSILS

Pedro Tamames, Juan Torre y Diego Rodríguez

There are 2 ways of analysing evolution

• Fossils– Early discoveries– Indication of interactions– Clues at cellular level

• Anatomical Observation– Analogous structures– Homologous structures – Vestigial structures

Early discoveries

Nicolas Steno (1638-1686)

Indication of interactions

Clues at cellular level

Analogous Structures

Homologous Structures

Vestigial Structures

When you have appendicitis the surgeon can take off the appendix as it doesn’t have any apparent use
