Cladograms

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on their shared characteristics.

Front

What does a common ancestor represent in a cladogram?

Back

A common ancestor in a cladogram represents a species from which multiple species have evolved.

Front

What is the purpose of a cladogram?

Back

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

Front

What trait is represented at point A in a cladogram?

Back

The trait at point A is typically a shared characteristic that distinguishes a group of organisms from others.

Front

What do the branches of a cladogram indicate?

Back

The branches of a cladogram indicate the evolutionary pathways and relationships between different species.

Front

What is the significance of the root of a cladogram?

Back

The root of a cladogram represents the most recent common ancestor of all the organisms depicted in the diagram.

Front

How can you determine the closest relative of an organism on a cladogram?

Back

The closest relative is found on the branch that diverges most recently from the common ancestor.

Front

What does it mean if two species share a trait on a cladogram?

Back

If two species share a trait on a cladogram, it indicates that they have inherited that trait from a common ancestor.

Front

What is a derived trait in the context of cladograms?

Back

A derived trait is a characteristic that evolved in the lineage leading up to a clade and distinguishes it from other organisms.

Front

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

Back

A cladogram focuses on the order of branching and shared traits, while a phylogenetic tree includes time and evolutionary distances.
