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.

Back

If two species share a common ancestor, it means they have evolved from a shared lineage and have common traits inherited from that ancestor.

How can you determine evolutionary relationships using a cladogram?

Back

You can determine evolutionary relationships by analyzing the branching patterns and shared characteristics of the species represented.

Front

What is the role of a common ancestor in evolution?

Back

A common ancestor is a species from which two or more different species have evolved, indicating a shared evolutionary history.

What type of information can be inferred from a cladogram?

Back

A cladogram can provide information about the relative timing of evolutionary events and the degree of relatedness among species.
