Absent notes U6 D5 Slide Deck Evolutionary Change

Open Ended

Explain how modern DNA technologies have transformed our understanding of evolutionary change compared to early methods based on physical characteristics.

Multiple Choice

Which DNA technology allows scientists to amplify (copy) specific DNA sequences for study?

• DNA sequencing

• Polymerase Chain Reaction (PCR)

• Genetic Mapping

• Comparing Genomics

Multiple Choice

What is the evolutionary significance of mutation analysis?

• It shows genetic relationships between species

• It reveals common ancestry

• It measures genetic changes over time

• It helps determine when species diverged

Multiple Select

Select all evidence types that help reveal common ancestry and evolutionary divergence.

• DNA Sequencing

• Comparing Genomics

• Mutation Analysis

• Physical Characteristics

Open Ended

Based on the amino acid sequences, what can be inferred about the evolutionary relationship of the human and the chimpanzee? Why?

Open Ended

What evidence supports your answer about which two species have a strong evolutionary relationship?

Multiple Choice

Based on the number of amino acid substitutions, which two species have a strong evolutionary relationship (or share a similar evolutionary history)?

• A and B

• B and C

• A and D

• D and B

Multiple Choice

Which species share more evolutionary history according to the number of similarities in a specific gene?

• B and C

• C and D

• A and E

• D and E

Multiple Choice

Which species show the biggest difference in their evolutionary history according to the number of differences in a specific gene?

• Species 1 and 4

• Species 2 and 4

• Species 3 and 4

• Species 4 and 5

Open Ended

Explain how phylogenetic trees and cladograms help scientists represent evolutionary relationships.

Multiple Choice

Which of the following is NOT a characteristic of a cladogram or phylogenetic tree?

• Shows evolutionary relationships

• Based on DNA analysis and fossil discovery

• Shows common ancestors and shared traits

• Shows the geographic location of species

Open Ended

Explain how branching points (nodes) in a cladogram or phylogenetic tree help scientists understand evolutionary relationships.

Multiple Select

Select all the features that are used to determine evolutionary relationships in a cladogram.

• DNA analysis

• Shared traits

• Geographic location

• Speciation

Open Ended

How does the process of speciation lead to the formation of new species according to the diagrams?
