Cladogram Practice

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among a group of organisms based on shared characteristics.

Front

What does common descent mean?

Back

Common descent describes how a group of organisms share a most recent common ancestor.

Front

What is an adaptation?

Back

An adaptation is an inherited characteristic that increases an organism's ability to survive and reproduce in its specific environment.

Front

Which organisms are most closely related according to a cladogram?

Back

Organisms that share a more recent common ancestor are considered most closely related.

Front

What type of characteristics are used to construct cladograms?

Back

Cladograms are constructed by grouping organisms together based on their shared characteristics.

Front

What is the significance of shared characteristics in cladistics?

Back

Shared characteristics indicate evolutionary relationships and help in classifying organisms.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that have similar functions but do not share a common evolutionary origin.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species.

Front

How do cladograms help in understanding evolution?

Back

Cladograms help visualize the evolutionary pathways and relationships among different species.
