Anthropology Lab 3: Common Ancestors in Order Primata

1. Upload the table
2. Upload the cladogram
3. Answer all exercise questions on this google form(one- three sentences)

Question 1: How many common ancestors can you identify on your completed cladogram?

Question 2: What are the derived trait(s) only shared by the two Homo species on your cladogram in comparison to the other organisms?

Question 3: Out of the 6 taxa on your cladogram, which organisms would you expect to exhibit a polygynous group structure (one male lives/mates with many females)?

Question 4: Proteins are made up of amino acids.The table below lists the amino acid sequences of three species for the protein myoglobin. The numbers represent positions on the myoglobin protein chain, and the letters represent which specific amino acids found at that position in the chain. (Ex. at position 7 H. sapiens display K).

Question 5: Does this reflect the relationships expressed on your cladogram? Explain why or why not

Question 6: Suppose you found symbolic behavior in T. gelada. Would this be more likely the result of homology or homoplasy?

Question 7: In your own words, explain why a derived trait might also be considered a primitive trait.
