What is a cladogram?

Back

A cladogram is 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 significance of a common ancestor in a cladogram?

Back

A common ancestor indicates that two or more species share a lineage and have evolved from a shared ancestor.

Front

What does it mean if two species are on the same branch of a cladogram?

Back

It means that they share a more recent common ancestor compared to species on different branches.

Front

What is the purpose of using cladograms in biology?

Back

Cladograms help scientists understand the evolutionary relationships and lineage of different species.

Front

What does the term 'derived trait' mean in the context of cladograms?

Back

A derived trait is a characteristic that evolved in the most recent common ancestor of a group and is not present in more distant ancestors.

Front

How can you determine the evolutionary relationship between two species using a cladogram?

Back

By examining the points where they branch off from the common ancestor, you can determine how closely related they are.
