Question 3

Answer 3

The Fossil Record:
Fossils: a record of the history of life on earth.

Homologous Body Structures: similar anatomy in different types of animals because of common ancestor.

Vestigial Organs: “leftover” traces of Evolution that serve no purpose.

Embryology; embryos of all vertebrates are very similar early on.

Biochemical Evidence:
Biochemistry: DNA with more similar sequences suggest species are more closely related.
