Study Notes

Comparative Anatomy

Comparative anatomy studies the similarities and differences between the anatomy of different organisms.

Structural Relationships

Homologous structures: similar in structure, but may have different functions.
Analogous structures: similar in function, but have evolved independently in different organisms.
Vestigial structures: structures with no function in the organism.

Embryology

Embryos of different species show similarities, which can be used to track evolutionary relationships.

Fossil Record

Fossils provide structural evidence that can be pieced together to understand evolutionary relationships.
