Cladograms

Front

What is a cladogram?

Back

A diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What is the purpose of a cladogram?

Back

To map the ancestral relationships and shared traits of different organisms.

Front

What do organisms on a cladogram to the right of a common ancestor share?

Back

They share common characteristics inherited from that ancestor.

Front

What is a common characteristic of all animals to the right of the hagfish on a cladogram?

Back

Jaws.

Front

What do both squirrels and lions have in common that distinguishes them from other animals?

Back

They are both mammals.

Front

What is a node in a cladogram?

Back

A point where a branch splits, representing a common ancestor of the descendant species.

Front

What does a branch represent in a cladogram?

Back

A lineage or evolutionary path of a species.

Front

What is the significance of shared derived characteristics in cladistics?

Back

They are traits that are shared by a group of organisms and are used to determine evolutionary relationships.

Front

How can cladograms be used in biological classification?

Back

They help classify organisms based on their evolutionary history and relationships.

Front

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

Back

A cladogram focuses on the branching order and relationships, while a phylogenetic tree includes information about the time of divergence.
