13.5 Read through this section and define the following terms:
Biogeography:
Comparative anatomy:
Homologous structures: Describe the concept and color the corresponding bones the correct color.
Why is comparing early stages of development important?
Vestigial Structures: Describe and give examples
Molecular Biology: ________ and _____________can be used by molecular biologist to determine common decent.
How do siblings compare genetically?
If two species have homologous genes with sequences that match closely, we can conclude_____________________
_______________________________________________________________________________________________
All forms of life use the same ______________________________________________________________________.
Thus __________________________________________________________________________________________.
13.6 Homologies indicate patterns of descent that can be shown on an evolutionary tree
Which two organisms on the tree are most closely related?
What three homologies do they have in common?
Explain why mammals and snakes are more closely related than mammals and amphibians.
How are evolutionary trees created?
Are they absolutely correct? Explain.
