How do we compare organisms?
Cuvier and Owen
Richard Owen (Structuralism)

animal parts cannot change indepently
George Cuvier (Functionalism)
Homologies
structure plans in organisms
Homology, Analogy & Homoplasy
Analogy
Different origin, similar function
Bird wings, insect wings
Homoplasy
Similar apareance, because of the evolution
Dolphins and sharks
Homology
Same origin, different function
Human arm, bat wing
Evolutionary Importance
Show us how many species have change
Helps us see how living things are related.
Helps scientists figure out why animals look or act the way they do
Why it is important to recognize these differences
Allows scientists lo predict evolution
Assists in identifying evolutionary pressures and environmental adaptations
Help us to know about evolutionary trees
Morphological Comparisons
Muscles
Atached and movement of it
Embryos
Look of the animal before they born
Bones and skeletons
sharpe, size and number of bones
