Exploring Cladograms and Classification

What is a cladogram primarily used for?

• To show the geographical distribution of species

• To illustrate evolutionary relationships

• To classify organisms based on physical characteristics

• To measure the genetic similarity between species

Which of the following taxonomic levels is the most specific?

• Class

• Order

• Family

• Species

In a cladogram, what does a node represent?

• A common ancestor

• A living species

• A mutation

• A geographical location

Which taxonomic level comes directly after "Order"?

• Class

• Family

• Genus

• Species

What is the primary difference between a cladogram and a phylogenetic tree?

• Cladograms show time, phylogenetic trees do not

• Phylogenetic trees show time, cladograms do not

• Cladograms are based on physical traits, phylogenetic trees on genetic data

• There is no difference

Which of the following is the correct order of taxonomic levels from broadest to most specific?

• Kingdom, Phylum, Class, Order, Family, Genus, Species

• Phylum, Kingdom, Class, Order, Family, Genus, Species

• Kingdom, Class, Phylum, Order, Family, Genus, Species

• Class, Kingdom, Phylum, Order, Family, Genus, Species

In a cladogram, what does a branch represent?

• A new species

• A lineage

• A genetic mutation

• A geographical barrier

Which taxonomic level is broader than "Genus" but more specific than "Class"?

• Order

• Family

• Phylum

• Species

What is the main purpose of classification in biology?

• To organize organisms into groups

• To determine the age of fossils

• To study the behavior of animals

• To map the distribution of species

Which of the following is not a characteristic used to construct a cladogram?

• Morphological traits

• Genetic sequences

• Behavioral patterns

• Geographical location
