How are cladograms constructed?

• By analyzing the characteristics of different organisms and determining their evolutionary relationships based on shared traits.

• By analyzing the DNA sequences of different organisms and arranging them based on similarity.

• By studying the geographical distribution of organisms and arranging them accordingly.

• By randomly selecting organisms and arranging them in a tree-like structure.

What are the limitations of cladistics?

• The limitations of cladistics include the reliance on available data, the subjectivity of character selection, and the inability to account for convergent evolution.

• Cladistics is not a reliable method for determining evolutionary relationships.

• Cladistics cannot account for horizontal gene transfer.

• Cladistics is limited in its ability to analyze extinct species.

True or False: Cladograms represent evolutionary relationships.

• False

• Cladograms represent genetic similarities

• True

Which of the following is not an assumption of cladistics?

• Any group of organisms will share a common ancestor at some point in the past.

• Organisms become increasingly more similar as they continue evolving from their cladogenesis point.

• Offspring diverge dichotomously in a process called cladogenesis.

• Organisms become increasingly different as they continue evolving from their cladogenesis point.
