Chapter 9 - Determining the relatedness of species

Question 1

Understand that we use various forms of evidence to determine relationships between species

Question 2

Give examples of homologous structures and explain how they arise

Question 3

State how vestigial structures provide evidence of evolution using an example

Question 4

Define molecular homology

Question 5

Describe the link between similarities in DNA or amino acid sequences between species and time since the species shared a common ancestor

Question 6

State why the differences in molecules can indicate time since a common ancestor was shared

Question 7

Explain why conserved proteins are more useful to determine the relatedness of species

Question 7

Explain whether the use of structural morphology or molecular homology will allow a more accurate understanding or relatedness

Question 8

Draw and label a phylogenetic tree indicating what nodes and lengths of lines represent

Question 9

Interpret phylogenetic trees to identify species that are more/least related to each other

Question 10

Interpret phylogenetic trees to identify when species shared a common ancestor
