Embryos, appendix, Thumbs
Tailbone, wisdom teeth, Vestigial whale pelvis
Phalanges, metacarpals, femur
hip bones, wisdom teeth, radius
What is a homologous feature?
adaptations created over time
Structures, like organs, that we have but don't use
Similar structures, like bones, between species
similar chromosomes
Comparative embryology provides strong evidence for common ancestry because
It shows how different species look similar in early stages of life
It shows the steps of development
It shows differences in how species develop
It is not a strong form of evidence for evolution
These structures are considered to be....

Comparative anatomy is...
study of DNA to determine if there is a common ancestor
study of behavior in organisms to determine common ancestor
