15 Questions
What does a phylogenetic tree represent?
Evolutionary relationships among different groups of organisms
What do nodes represent on a phylogenetic tree?
Common ancestors
Which statement best defines homology?
Similarity in traits due to shared ancestry
What is binomial nomenclature used for?
Naming species using two Latin words—genus name and species epithet
How does hierarchical classification organize organisms?
By grouping them into nested categories based on shared characteristics
What is the main purpose of organizing organisms into groups based on shared characteristics and evolutionary relationships?
To create a hierarchical classification system for all living organisms
In the domain Eukarya, which of the following is NOT a kingdom according to the text?
Archaea
How do homologous traits assist scientists in grouping organisms?
By helping to trace back to a common ancestor
Which component of Darwin’s Theory of Evolution emphasizes the differential survival and reproduction of individuals with advantageous traits?
Natural selection
What is the primary outcome of convergent evolution?
Independent evolution of similar traits in unrelated organisms
Why are analogous traits not indicative of shared ancestry?
Since they evolve independently in different species

"Descent with modifications"
"Different species face similar environmental challenges or selective pressures" is characteristic of what evolutionary phenomenon?
"Convergent evolution"
