Cladogram Analysis and Construction Quiz

What is the primary purpose of a cladogram?

• To show the exact evolutionary history of species
• To present a hypothesis of evolutionary relationships
• To illustrate genetic sequences of organisms
• To depict the geographical distribution of species

In the video, what criterion is used to determine the oldest species in the cladogram?

• The species with the most traits
• The species with the least number of traits
• The species at the top of the cladogram
• The species with the most complex traits

Why does the instructor emphasize not to 'fall in love' with the idea that traits must be in order?

• Because traits always evolve randomly
• Because the numbering of traits is arbitrary
• Because the complexity of traits doesn't necessarily correlate with their evolutionary order
• Because traits always evolve in reverse order

In the cladogram construction process, what does placing a trait number on a branch point indicate?

• The extinction of a species
• The evolutionary origin of that trait
• The complexity level of the trait
• The geographical location where the trait appeared

What is a key difference between a cladogram and an evolutionary tree, as mentioned in the video?

• Cladograms show exact time scales while evolutionary trees don't
• Evolutionary trees show extinct species while cladograms don't
• Cladograms focus on shared derived traits while evolutionary trees focus on overall similarity
• There is no significant difference between the two
